Her recent engagement is already old news, but Drew Barrymore is still aglow, especially when talking about fiancé Will Kopelman.

“I didn’t want to go to this little party, and my friend dragged me there and I met him,” the Big Miracle star tells Anderson Cooper on Friday’s Anderson. Though their initial meeting was several years ago, it wasn’t until 2011 that “things got serious.”

Now, after what Barrymore calls a romantic proposal, the two are in the midst of wedding planning — and all the fun that comes with it. “The thing that I think we’re the most excited about is … this will be such a nice year to do wonderful things together,” she says. “We like to spend time with our friends anyway, so on the auspices of this kind of a celebration, even more heightened and wonderful. What a great adventure.”

In the meantime, Barrymore also gets to show off her ring, a 4-carat sparkler from Graff Diamonds. “It’s beautiful,” she says. “[Kopelman] picked it out and he’s just got lovely taste, and it’s really fancy. I’m sort of like funky, eclectic girl so I feel like this is very fancy and I’m trying to like, you know, feel comfortable with it.”

She also needs to remind herself to stay comfortable with the planning process. “The worst thing you can do is like stress about things, and I totally fall prey to stress and lose my own advice every once in a while,” she admits. “We’ll just have a wedding, we’ll get married, it will be very calm.” Check out the clip below for more, and catch Anderson Monday through Friday at 4 p.m. EST.

Considering Drew Barrymore‘s new fiancé Will Kopelman is an art consultant, it’s no surprise that the actress’ brand-new engagement ring is truly, well, a work of art.

The ring features a colorless radiant-cut diamond — which weighs in at just under 4 carats — situated on a diamond-covered band. The stunning sparkler was designed by Graff Diamonds, though “[Kopelman] picked it out,” a source tells PEOPLE.

Kopelman and Barrymore have been linked romantically since February of last year. The couple got engaged in Sun Valley, Idaho, while vacationing over the holidays.

This will be the third walk down the aisle for Barrymore, who was married to Tom Green in 2001 and to Jeremy Thomas briefly in 1994. Tell us: What do you think of Barrymore’s ring?

Bye bye, red — hello again, ombré! Drew Barrymore appears to be back on the two-tone hair wagon again after dying her hair red in April. The actress — who hasn’t been out in a while — joined pals Cameron Diaz and Kate Hudson (plus Reese Witherspoon) at the LACMA Art + Film Gala Honoring Clint Eastwood in L.A. on Saturday, debuting her new (and also short) do at the event.

In April, Barrymore’s colorist Tracey Cunningham told PEOPLE that the actress prefers to keep her look fresh. “We like to try new things when the seasons change,” she added. Since the auburn was “the perfect spring red shade,” Cunningham said, it’s possible Barrymore’s short dark-to-light is what’s hot again for fall. Not that it matters for the star; as Cunningham said, “Drew is a color chameleon! Her skin is so pretty that any hair color will complement her eyes.”

And in fact, she has tried just about every color under the sun: in September of 2009, the actress worked light blonde hair with black tips while promoting her film Whip It, then moved on to practically a reverse color scheme, sporting darker roots with lighter ends, a look she owned for quite some time. She’d previously sported red hair in 2007 and 2008, as well. Tell us: What do you think of Barrymore’s return to ombré hair?

TRY STAR HAIRSTYLES ON FOR SIZE IN ‘INSTANT MAKEOVER’

For her first foray world of music video direction with Best Coast, one of her favorite bands, Drew Barrymore had one singular vision: “How do we make the most killer video?”

Drawing her inspiration from movies — “I love The Outsiders, The Warriors and West Side Story,” she shares — Barrymore confesses to PEOPLE that her preparations for a the video were exhaustive. “Ugh. I’m Tracy Flick to the nines,” she admits, referring to Reese Witherspoon’s iconic Type-A nerd in Election.

Not so nerdy? Her cast. Barrymore, a veteran child actor herself, assembled a veritable who’s who of up and comers including Kick-Ass‘s Chloe Moretz, Teen Wolf‘s Tyler Posey, Community‘s Donald Glover, The Secret Life of the American Teenager‘s Shailene Woodley and Alia Shawkat, the “muse” from her feature directorial debut, Whip It. She included Miranda Cosgrove as well, hoping to make a departure from the actress’s sweet iCarly look. “I really wanted to change up her look — the makeup, the clothing and the attitude,” Barrymore says. “She was willing to play.”

Her fashion inspiration came from one simple element: “A jean jacket — it totally transcends,” she explains. “It works in the ’50s, it was punk rock in the ’70s, it was grunge in the ’90s. I wanted to bring in that timeless quality.”

For color, she looked to another iconic fashion piece: “I love James Dean’s jacket in Rebel Without a Cause, like that pop of red is so beautiful so I put that on Tyler.” The results? One vintage-inspired yet current video that tells quite a love story.

Barrymore’s next project as a director, a feature called How to Be Single, came to her toward the tail end of her own time as a single lady (she’s been dating art consultant Will Kopelman for several months). “I was single for over a year,” she shares. “I’m at the perfect time in my life to discuss this.” Known for assembling stellar casts in projects such as He’s Just Not That Into You, Barrymore says she’s not allowed to share any names yet, though. As she says, “I’d get in trouble!”

Sitting atop a smoking car, her bright red hair fanned out behind her, Drew Barrymore makes quite an impact as the face of Neiman Marcus‘s “The Art of Fashion” campaign. The actress poses in a series of photos for the retailer, modeling looks from designers like Akris and Valentino in ads that will appear in the September issues of Vogue, Vanity Fair and W. “The shoot tells the story of a star’s transformation,” Eddie Nunns, vice president of Neiman Marcus brand creative, tells WWD. “We felt that Drew Barrymore possessed not only the pedigree and glamour of old Hollywood, but also the confidence and spirit of the modern-day woman — much like Neiman Marcus itself,” he adds in a statement. Shot by Norman Jean Roy, this is just the second Art of Fashion campaign to feature a celebrity; Jennifer Jason Leigh served as the face for the inaugural promotion in 1994. According to Nunns, Barrymore was quite involved with the operation, right down to the hair styling. “She’s a powerful, modern woman with trans-generational appeal,” he says. “The project … beautifully captures the essence of Neiman Marcus’s edits of the fall collections.” –Kate Hogan

SHARE YOUR THOUGHTS ON STAR LOOKS IN ‘FASHION FACEOFF’

With the intense heat and sizzling sunshine, we can’t even fathom summer’s end just yet. There are still trips to take, frozen treats to eat and shoes to buy! But with Labor Day creeping up ever so quickly, thoughts begin to turn toward cooler weather and fall fashion. When stocking up on styles for your post-summer wardrobe, do you consider white? Though it was once considered taboo to go so light anytime between Labor Day and Memorial Day (or in some cases, perhaps Easter), stars and civilians alike have defied the trend in recent years. Drew Barrymore, Cameron Diaz and Blake Lively all stepped out in white in April, and not one fashionista blinked an eye. So why not rock white pants at a fall fête, don a snowy dress to a winter bash or warm up in a stark white sweater? Though it may still feel like breaking the rules, weren’t rules meant to be broken? Tell us: Do you wear white after Labor Day?

Talk about a ravishing redhead! Drew Barrymore recently made a hair hue switch, picking up a warm red color and leaving her ombré locks behind. We love the new look, but wanted to know — why the switch? According to Barrymore’s colorist, Tracey Cunningham, it was just time for a change. “The ombré look really created a great beauty buzz but we wanted to try something new,” Cunningham tells PEOPLE. “Drew likes to keep her look fresh; we like to try new things when the seasons change.” Choosing to use “the perfect spring red shade” — which she describes as soft and warm, with “great vibrancy” — was easy, Cunningham says. “Drew is a color chameleon! Her skin is so pretty that any hair color will complement her eyes.” To make such a change on your own, Cunningham recommends taking the process slowly. “When you book your appointment, be prepared to spend some time in the salon,” she explains. “The color needs to be gradually added back in; your colorist has to make sure they apply the color with perfect technique to even out the look and void the prior ombré look.” To lock in color and shine, Cunningham recommends a glaze, too. But if you’re gunning for a major change of your own, think twice, the stylist says. “Do it when the time is right! Don’t try a radical change two weeks before your wedding or a major event in your life,” she cautions. “Give yourself time to adjust to the change — and embrace it!” –Reporting by Katherine Kluznik Rentmeester

Barrymore’s literally rocked every hair color under the sun, but with this new hue, she returns to a glam look we saw (and loved!) in 2007 and 2008.

Drew Barrymore has been rocking ombré hair for well over a year now, but this weekend she put a dramatic spin on the dyed-and-true trend. Barrymore’s dark-rooted style has long been her signature look, but in the past she favored a more subtle take on the trend, with brown roots that graduated slowly out to warm blonde tips. This Sunday, however, the actress stepped out for the Chanel & Charles Finch pre-Oscar dinner in Los Angeles sporting hair that ranged from almost raven at the roots to baby blonde at the tips.

While promoting her new film Going The Distance in the U.K., Drew Barrymore is skipping the glitz and glam for hippie-inspired hair and hemlines. On Thursday, the free-spirited star was seen trotting around London in a white floor-length dress toughened up with an All Saints leather jacket and biker-chic accessories. The next night, Drew took a ’70s-inspired approach, stepping out of her London hotel in shimmering skinny pants, a belly-baring fuzzy cape and platform pumps. And on Saturday, Drew took boho chic to new heights, posing at the V Festival in Staffordshire in a floppy hat, paired with a beaded-fringe top, slouchy olive green pants and brown leather boots.
