Gallery: Rihanna and Katy Perry come out to play at the Nickelodeon Annual Kids’ Choice Awards

While British celebs were donning their best dresses for the Empire Film 2010 awards last night, their US couterparts were showing off their casual style on the red carpet of Nickelodeon‘s 23rd Annual Kids’ Choice Awards.

Popstar Rihanna, Tyra Banks and Katy Perry all toned down their usual red carpet glitz to take part in the awards, but despite that they all looked stunning.

The celebs were also joined by Brit stars Pixie Lott and Mel B, who looked just as good as their US style enemies.
