The 'I Kissed A Girl' singer is all smiles as she attends charity event in Las Vegas this weekend.

Katy Perry was pictured looking glamorous and happy as she hit the red carpet for the first time since news broke of her forthcoming divorce to husband Russell Brand.

The 'Teenage Dream' singer was sporting her new blue hairstyle and an elegant short black dress as she posed for pictures with designer and good friend Markus Molinar in Las Vegas over the weekend.

The star was in attendance for the jewellery designer's charity event at The Mirage Hotel's 1OAK nightclub and completed her outfit in an over-sized pair of steel capped high heels.

The star has rarely been pictured since the announcement of her marriage breakdown at the end of last year and recently wrapped up her worldwide 'California Dreams' world tour with shows in the Philippines and Indonesia.
