Katy Perry - Katy Perry Dyes Hair Blue After Russell Brand Split

The singer, 27, is thought to have been filming an Adidas commercial in Los Angeles when the snap was taken on Thursday evening (January 12, 2012), and later obtained by People magazine. It shows the Fireworks hitmaker putting on a brave face and posing with an admirer while sporting blue hair and a blue Adidas sports jacket. Though the pop star chose not to attend the People's Choice Awards earlier this week, sources say she seemed in high spirits at the Adidas shoot. To be fair to Perry, she was one of several high profile stars who failed to attend the annual bash - R&B beauty Rihanna chose instead to attend an Nba game played just across the street from the awards ceremony, while Kim Kardashian was also absent despite winning an award for best celebrity.

The Hollywood world was stunned over the holiday season, when it was announced comedian Brand had filed for divorce from the Californian singer after just 14 months of marriage. There has been suggestion the pair failed to sign a prenuptial agreement, and therefore could split their fortune 50/50.
