Katy Perry Bares Her Toned Tummy In Green Get-Up

Katy Perry's tight tummy has us green with envy!

The "Part of Me" singer walked the orange carpet at the 2012 Kids' Choice Awards in a slime green-colored top, skirt and matching heels. No one can deny, the 27-year-old songstress looks sexy and fierce ... even with the long purple and blue ponytail!

Ms. Perry, who won an award for Favorite Voice from the movie The Smurfs, was also up for Favorite Female Singer. But no fireworks for Katy! Selena Gomez walked away with the award.

Wondering when Katy's going to ditch the funky hair and get back to the basics? We know girls just want to have fun, but that blue hue could use a touch up!
