Katy Perry: Ready to Let Loose in Sin City

She’s been lying relatively low since news surfaced of her divorce from Russell Brand, and now Katy Perry is ready to party again.

The “Hot N Cold” singer will be making her first official post-split appearance in Las Vegas on Friday (January 27) for the grand opening of 1 OAK Las Vegas at the Mirage Hotel.

In addition, the event will also be a benefit for the GiveLove charity, co-founded by Patricia Arquette and Rosanna Getty.

Earlier this month, Katy backed out of her appearance at the People’s Choice Awards, as she wasn’t ready for a high-profile appearance just yet.
