Stars were feeling the blues on Thursday afternoon, stepping out across the globe in the best and worst of the classic color. Rachel Bilson showed off her taut tummy in Los Angeles, pairing a super tight red top with baggy denim shorts and finishing the look off with metallic wedge sandals. Rebecca Gayheart also tried out the baggy short trend, but wasn’t as fortunate when it came to body-flattering fit, resulting in an awkward look for the former Neutrogena girl.

Sharon Stone dove into a super chic, multi-blue hued shift dress, which she jazzed up with a turquoise necklace. Jessica Alba also used the cool color in the form of a scarf, which added some pizzazz to her jeans and t-shirt.

When they weren’t on-stage collecting surfboards, the stars at the Teen Choice Awards were getting gifted – and giving – backstage at the MOROCCANOIL celebrity retreat.

Twilight’s Ashley Greene made a bee-line for the Moroccanoil display where she loaded up on the new light hair oil and cast her vote for Much Love Animal Rescue.  The LA based charity will receive a portion of a ten thousand dollar contribution from MoroccanOil. Farm Sanctuary and The World Wildlife Fund will also share in the cash donation thanks to votes from stars like Katy Perry, Russell Brand and Chace Crawford.

Hello Kitty by Sanrio went all out for super-fan and Teen Choice Awards host Katy Perry. The singer – known for her adoration of all things Kitty - was treated to a surprise when she entered her dressing room on show morning to find it made over into a Hello Kitty Fantasy Land.  She tweeted a photo within minutes and said “Hello Kitty threw up in my dressing room @ the TCA'S”

RadarOnline.com blogger Jason Derulo stopped by the Mastermind table to test his skills.  The What Cha Say singer loved the game and said he REALLY loved knowing that games would be donated to City of Hope's children's hospital for each star that played.

Sandra Bullock, Katy Perry, Russell Brand, Cory Monteith, Travie McCoy, Ashley Greene, Jackson Rathbone, David Archuleta and Levi Johnston received a YEARS supply of their favorite flavor of 5 “REACT.”

And twice dumped Levi Johnston continued to enjoy his fifteen minutes of fame as he made his way around collecting gifts including the new slimmer Palm Pixi which Levi said he needed because, “You can’t wear your skinny jeans with the Palm Pre.”
