Katy Perry Debuts Light-Blue Locks In Vegas

Pop star shows off new 'do at a Las Vegas charity event.

Katy Perry is feeling a little less blue these days. The pop star began rocking an electric-blue bob not long after news broke that husband Russell Brand had filed for divorce late last year. But Perry, who stepped out in Las Vegas this weekend, appears to have dipped her locks in the dye once again.

On Friday night, KP hit a charity event dressed in a beaded frock, her razor-cut 'do colored in a rich turquoise. The party at the Vegas outpost of nightspot 1OAK was hosted by GiveLove.org, an organization devoted to improving public health in Haiti.

But although newly separated Perry reportedly put on a good face, one source told amNewYork the "Waking Up in Vegas" singer seemed "subdued." The pop star "pretty much sat in the same spot the whole night" as her friends danced, according to the source.

While Katy has always been adventurous about her hair hues, post-split, she seems, anecdotally at least, to be hitting the bottle — of dye — with increasing frequency.

Brand and Perry announced the end of their marriage on December 30, after 14 months together. The exes have been a keeping a rather low profile ever since. The comic is set to perform on March 4 at New York's Radio City Music Hall as part of an Amnesty International benefit, while Perry may turn up next at the Grammy awards on February 12, where she's up for two statues. She was spotted earlier this month shooting an Adidas ad, not long after wrapping two concert dates in Indonesia and the Philippines.
