The 26th Annual Nickelodeon Kids’ Choice Awards are going down Saturday night in Los Angeles -- and, while it’s a show for small children, there’s some BIG star power in the building.

But were they dressed appropriately for the show?

Katy Perry brought her famous cleavage (and bare midriff) to the red carpet ... but, for her, that's really nothing new. Kristen Stewart was showing her own skin of choice, once again showing off legs in a cute pair of shorts.

Khloe Kardashian looked amazing in a simple white dress, while Ke$ha had our favorite outfit of the night -- one inspired by "Dumb and Dumber." Plus, bringing her younger brother as her date was downright adorable ... and very appropriate.

Other sightings included a single Selena Gomez, Jaden and Willow Smith, Victoria Justice and more.

Keep checking back for more photos as they come in, we'll keep updating the gallery!
