Katy Perry will be hosting the 2010 Teen Choice Awards. Along with her hosting duties, Katy Perry will also performing this year as well. I am guessing she will be performing California Girls again as she did at the MTV Movie Awards this year with Snoop Dog. Teen Choice Awards 2010 will air August 9, 2010 at 9 pm ET/PT.
