Britney Spears tweeted a photo on Tuesday from the new ad campaign for her latest perfume "Fantasy Twist." In the glamorous black and white shots, Britney is seen in two very different lights! Plus, Blake Lively looked stunning when she made her first post-wedding appearance at the Chanel Bijoux De Diamant 80th Anniversary bash in NYC, and Christina Aguilera showed off her body in a purple figure-hugging frock at the AMA nominations in Los Angeles on Tuesday.
