Hollywood Celebrates at the Kids' Choice Awards

At last night at the KCA's, hosted by Jack Black, it was a mish-mosh of Young Hollywood (with the exception of Cameron Diaz). On the fashion side, it was an okay night, Hayden looked better than Rihanna in my opinion. But take a look for yourself:

{Hayden Panettiere in Leila Azhar; completely appropriate and adorable}

{Rihanna in an H&M top and Stella McCartney jeans; I like each alone, not together}

{Ashlee Simpson in Alexander McQueen; it's classy-punk, I love it}

{Cameron Diaz in Missoni; perfection, trendy and right for the event}

{America Ferrara in David Meister; lovely, but too fancy & hate the wedges}

{Emile Hirsch in Vans shoes; he might as well not wear clothes, he's so hot}

{Shia LaBeouf also in Vans sneaks; love his whole getup, especially the cardi}
