Gracing magazines is nothing new for Salma Hayek, but now the actress is venturing into literature with an appearance on the front cover of hairstylist Robert Vetica’s book, Good to Great Hair. At Thursday’s Moroccanoil-sponsored launch party for the tome, which offers hairstyles and advice based on hair type, the star, who wrote the forward to the book, revealed what led her to become involved in the project with Vetica, whose other A-list clients include Jennifer Lopez, Marion Cotillard, Mariah Carey, Renee Zellweger and Naomi Watts. “I think it’s great that women can get ideas of what is best for them without having to go to somebody who’s super-expensive like Robert is in real life,” she told PEOPLE. Another famous fan, Debra Messing, said that Vetica encouraged her to love her curly locks. “Every day was an interesting hair moment growing up,” she revealed. “One of the first things that Robert taught me was that it was not a disaster. He was like, ‘Your hair is fabulous and it could do anything!’” she says. Hayek, added, “When he does my hair for an event, the blow-dry lasts for four or five days. I don’t know how he does it, but I have great hair for the whole week once he does it for one day!” But forget hair for a minute, what is the secret to Hayek’s glow? “I am happy,” the newlywed said with a sly grin.

Good news for Mariah Carey fans. The singer has just announced that following the success of her first scent last year, she will be launching a new sparkling floral this September. Luscious Pink by Mariah Carey will have notes of Tahitian tiare flower — just like the original M by Mariah Carey scent — but will change it up with a bouquet of lily of the valley, pink peony and a touch of white musk. As for why she decided to create a second scent with Elizabeth Arden, Mimi reveals, “Launching my first perfume was such an amazing experience that it has inspired me to expand my fragrance collection.” But it’s the newlywed’s description of Luscious Pink as “an ethereal…scent that reflects the delicately sensual, feminine and optimistic side of me that is so present today in my music, my fragrance and my life,” has us intrigued.

Two iconic singers known for their high heels and micro hemlines, but when it comes to throwing out the first pitch in style, who strikes out? Victoria Beckham memorably stepped up to the pitcher’s mound at Dodgers Stadium last summer in short-shorts and Dries Van Noten wedge sneakers. And this week, Mariah Carey just may have one-upped her in platform heels, denim cut-offs and a tummy-baring satin jacket. While both women clearly spent more time picking their shoes than working on their curveball, we have to pick a winner in this instance — isn’t that what sports is all about? Tell us: Whose baseball style do you like better? Posh or Mariah?

What does one of the hottest stars wear after her out-of-the-blue island nuptials? Just some hot little bikinis, if you’re Mariah Carey. Just before the wedding took place, Mariah’s stylist hit the stylish Pesca boutique in New York to pick up a few things “for a trip that came up all of a sudden,” according the store’s owner. Mariah’s honeymoon must-haves are multiple bikinis from Beach Bunny Swimwear that are “colorful and fun and sexy,” including the “Lady Lace,” $209, the “Sweet Escape,” $240, the “Beautiful Stranger,” $239 and the embroidered “Secret Garden,” $294. And of course, a pink Debbie Katz cover-up since “Mariah loves pink!” Click here to see the first photos of Mariah’s wedding to Nick Cannon.

By now we all know Mariah Carey’s obsession with sky-high heels, and she seems to be able to overlook the pain or potential for stumbling that comes with stilettos, even in these five-inch-plus Giambattista Valli platforms. She may have needed an extra hand to walk without falling, but Mariah’s not the only one willing to put up with pain in the name of style. Whether it’s torturing our feet for the sake of fashionable heels or going through painful beauty procedures to achieve glowing skin, everyone’s got a story. Now the editors at StyleWatch want to know about your sacrifices for fashion. Tell us: What’s the most pain you’ve endured in the name of fashion or beauty and why? Was it worth it?
