Blake Lively: "I Eat Cupcakes and Don't Work Out!"

Blake Lively: "I Eat Cupcakes and Don't Work Out!" The secret to Blake Lively's bombshell bod? There aren't any, apparently. At a screening of Oliver Stone's Savages in NYC Wednesday, the leggy Gossip Girl star, 24, told Us Weekly she's not the most diligent when it comes to keeping up an exercise routine -- or eating her fruits and veggies.

"I eat cupcakes and I don't work out!" Lively admitted, laughing. "But if you ask me in ten years, I'm going to regret answering that way now . . . I don't even drink water. It's terrible!"

And though she's a fixture on Best Dressed lists now (Lively rocked a bright yellow Gucci frock for the screening), Ryan Reynolds' girlfriend of eight months assured Us some of her high school style choices were questionable, at best.

"[I did] that whole Abercrombie denim skirt with Uggs thing," Lively confessed of her teenage wardrobe. "That was a problem!"[usmagazine.com]

Elle Fanning, Blake Lively and Serena Williams Go For a Dip

We're feeling inspired to go swimming this weekend (or at least watch "The Little Mermaid," depending on how these thunderstorms go) due to the aquatic dresses celebrities donned this week. Thirteen-year-olds and tennis stars alike joined in on the mermaid look.

Elle Fanning wore a Marc Jacobs resort 2012 dress and Chanel platform slingbacks -- proving her impeccable red carpet style once again -- at the 2011 Women in Film Crystal + Lucy Awards. She went no-frills with a slicked-back ballerina bun.

Blake Lively shone in a Tibi Spring 2011 dress to promote her new film "The Green Lantern" on the "Today" Show. She put her blond-again hair half-up and wore the rest wavy for a laid-back look that perfectly complemented her structured frock.

Serena Williams donned a Burberry dress with Nicholas Kirkwood heels and pink lips (stars' new favorite trend?) at the WTA Pre-Wimbledon party in London. With her dark curls hanging loosely around her face and her metallic blue eyeliner, Williams could have easily passed for a glammed-up mermaid -- although we imagine those heels would be a little hard to swim in.[stylelist.com]
