Katy Perry brought a change of clothes
was blasted with slime at the Nickelodeon Kids' Choice Awards
The singer was tricked into opening a box that catapulted goo all over her.
She was on stage to present the Favourite Movie Actress prize at the event in LA on Saturday.
But Katy didn't seem to mind - she was all smiles as she slid around in the green stuff.
She even joked with the winner, Hannah Montana star Miley Cyrus, 17.
She chased after her and tried to give her a slimy hug.
‘I can't see anything,' said the 25-year-old. ‘Why does it taste like boogers?'
Katy gave teen singer Justin Bieber a peck, once she got cleaned up.
‘Told you I would tap that. Yummy,' she wrote as a caption for a picture on Twitter.
Katy later headed to Perez Hilton's 32nd birthday party, arriving on an elephant.
