You know you've made it big in Tinsletown when you've been slimed at the Nickelodeon's Kids' Choice Awards.And this year's recipient was none other than Kary Perry who was almost knocked over as she was hit by a box full of green gunge at the ceremony in Los Angeles yesterday.

The I Kissed A Girl singer went up to the podium with actor Jonah Hill to present the award for Favourite Movie Actress.But as she walked over to a stand to open the box to announce Miley Cyrus as the winner, it exploded in her face, covering her from head to toe in network's signature bright green gunge.

Katy, 25, was expecting to be hit, but still managed to look genuinely surprised as she was drenched.After wiping the slime away from her eyes, Perry moaned: 'I can't see anything. Why does it taste like boogers?'
