Where did the biggest stars of the Grammys go after the show? To party with InStyle! We teamed up with Warner Music Group—along with Heineken and Mini Cooper—to co-host a post-Grammys bash at the Chateau Marmont in West Hollywood, where stars including Amy Smart, Alessandra Ambrosio, and Abbie Cornish (in Roland Mouret) stopped by to celebrate music’s biggest night. “I love music and grew up with music,” Cornish told InStyle.com. “For me, music comes from the very beginning of my childhood. My parents played certain CDs, and they stay with you.” Rocker Sting, who attended with wife Trudie Styler, kept up the high energy of the night following his performance with Bruno Mars and Rihanna during the Bob Marley tribute. “I thought it was a really great show,” Sting said. “The acts were great and the atmosphere was wonderful, and I was very happy to be part of it.” Click through to see more stars who celebrated the Grammys with InStyle!

Ever wonder what it’s like to have a professional stylist create a perfect look just for you? “Heaps of fun!” according to Abbie Cornish, whose new crime comedy, Seven Psychopaths comes out tomorrow. She has loads of public appearances to promote the film, and every event requires a new look. So she teamed up with uber-stylist Jessica Paster—who also works with Emily Blunt and Jenna Dewan-Tatum—to help her pick out her wow-worthy ensembles, like the Roland Mouret, Reem Acra, Giulietta, and Emilio Pucci outfits above, from left to right. “I love working with a stylist who knows what’s good and what isn’t, what’s right for your body and what isn’t,” Cornish told InStyle.com at the after-party for her movie at No. 8 in New York City, hosted by the Cinema Society & Hugo Boss. “I’ve gone through phases where I’ve done it myself, and it’s such hard work. To try on a bunch of clothes and pick out an outfit with another girl is heaps of fun. Who doesn’t want that?” Choosing the Roland Mouret gown for last night’s New York premiere was a “no-brainer,” she said. “This dress is so easy to wear, and it’s beautiful–kind of like a painting,” she added. “Roland Mouret shapes dresses for women so beautifully. He just totally gets the woman’s body and accentuates it. I’m a big fan.”
