Heidi Klum didn’t plan on walking the runway of the Victoria’s Secret Fashion Show last night, but let’s just say she’s a little bit impulsive. “I felt great the night of the fashion show and decided last minute to walk,” the supermodel, 36, who welcomed daughter Lou, with husband Seal, last month, tells PEOPLE exclusively. Klum, who had already been fitted for her dress, opened the Enchanted Forest-themed part of the show, wearing a vine-strewn corset and a full white skirt. “I loved my outfit,” she says, “so I thought, why not?” Her surprise appearance, known only to Victoria’s Secret insiders, drew screams and applause from a shocked audience during the live show Thursday night. Though Klum, who was expected only to host the festivities, said that while her new job behind the scenes meant there was “definitely less pressure,” walking in the show was a thrill for her. “I’m proud of being the curvy model on the Victoria’s Secret stage,” she says, adding that she enjoyed the show herself. “The Black Eyed Peas and all of the looks for the show were fantastic!” You can watch Heidi — and all the Angels — hit the runway when the Victoria’s Secret Fashion Show airs on CBS at 10pm EST on Dec. 1.–Charlotte Triggs

We’re all for a little style experimentation, but when we spotted beauty mavens Ashley and Mary-Kate Olsen at MoMA’s Film Benefit honoring Tim Burton this week in New York we were more than a little perplexed. We’d gotten used to Mary-Kate being the style risk-taker and her twin Ashley taking a more conservative approach. But the duo played with our expectations, with Ashley adding rainbow stripes to her hair and her sister going as bold as ever with the deepest red lips around. Tell us: What do you think of the sisters changing it up? What’s the boldest look you’ve tried in the name of beauty?

She’s a successful TV star, fashion designer and fiction writer, but she hasn’t written a book on style — until now. Lauren Conrad will unveil her top style tips in Lauren Conrad Style, to be published by Harper Collins in the fall of 2010. The book will not only feature new and never-before-seen photos of the fashion icon, but the former MTV “Hills” star will show readers exactly how to interpret her classic and cool style into their lives. “I am really excited to write a style guide,” said Conrad, who designs an affordable clothing line for Kohl’s, in a release. “I think fashion should be fun and reflective of who you are. When you wear clothes you feel good in, it shows in everything you do. I know this guide will offer simple, practical tips to help anyone look fabulous.” This year, Lauren released her first book L.A. Candy, which was a #1 New York Times bestseller; her follow-up novel, Sweet Little Lies, goes on sale Feb. 2, 2010 (for more information on Sweet Little Lies and Lauren’s 10-city book tour, go to harperteen.com).

If Leighton Meester could give just one piece of fashion advice to her Gossip Girl alter ego, Blair Waldorf, what would it be? “She could let loose a bit,” British Glamour’s December cover girl says. “She’s always got every bow in the right spot and her headband perfectly placed. Tights to match her sweater to match her jacket to match her gloves to put on with her hat.” It sounds…exhausting. However, despite their different wardrobes, the Gossip Girl actress credits the show for her own edgy style. “This character has been an introduction to fashion,” she says. “I take my own cue and do something different. Blair’s much more classic – I like changing it up.” When it comes to her beauty regime, the actress ditches Blair’s rollers and irons for a more natural look. “I actually think I’m prettier without makeup,” she boldly states, and her favorite hairstyle is definitely headband-less. “I like it to be somewhat tousled.” Perhaps the only fashion item they do have in common is their love of gravity-defying high heels which, according to Meester, are responsible for her toned calf muscles. “It’s probably from walking in high heels — I’m not kidding!” –Monique Jessen

Well, her boyfriend Russell Brand loved them. Now, lusty fans can have some too. Katy Perry’s soccer-themed lingerie, that is! Brand’s favorite soccer club, West Ham United, provided three shirts for 25-year-old Perry’s stylists to fashion into skimpy stagewear for her turn hosting the MTV Europe Music Awards earlier this month. And after the pictures raised eyebrows for her boyfriend, as well as admirers around the world, the club in East London has decided to make a limited number themselves. Initially, 50 sets priced at around $480 each will be made on a pre-order basis only. (If placed before November 20, they will be ready for Christmas and they are ordered before the end of next month, they will be perfectly timed for a Valentine’s Day surprise, the club says.) Perry’s get-up was the brainchild of freelance celebrity stylist and costume designer Siobhan Dillon. She told the West Ham United website Wednesday, “I thought it would be cool to try and make the shirt as football-oriented as possible. “So, I used the collars along the top of the brassiere and used the two badges on the front. I had a team of three girls working with me on the outfit. It was made entirely from the three shirts, but we had to take the Airtex out and replace it with some lining.” Contact West Ham United for your own set here. — Simon Perry

In her new film Broken Embraces, Penélope Cruz dresses the part of a mogul’s wife and budding movie star, but at the Calvin Klein Collection-sponsored Cinema Society premiere at the Crosby Street Hotel last night, she looked simply angelic in a long white velvet coat and matching dress from Calvin Klein Collection with glittering Chopard diamonds. “She’s an angel,” said Francisco Costa, who is the Women’s Creative Director, Calvin Klein Collection. “She’s a total clothes horse. She looks amazing in everything.” Costa was also struck at how well the camera reacts to Penélope, even in her off time. “It was quite telling today. I wasn’t in the last fitting, and I got pictures of her in the clothes at the hotel room. And they looked like movie stills. She was just wearing the clothes in the hotel room, but it almost felt like Helmut Newton pictures, there was so much of her in the photos.” Even for a star as graceful as Penélope, it is still demanding to promote two movies at once — her musical Nine is coming out in December, as well. “Well, yes, I’m dressing for two tours at once over these two weeks, so it’s great that I have a team of people that help me.” Luckily after months of rigorous training for her dance numbers in Nine, she looks as fabulous in her red carpet clothes as she does in her revealing costumes. “For Nine, I had to rehearse a number for three months,” said Cruz. “That was the only way to do that, I had singing teachers and dancing teachers. I did dancing when I was growing up. I did classical ballet, but what I do in Nine is a VERY different type of dance. It was really like starting from zero, in a way.”–Jeffrey Slonim
