Pop star Katy Perry has received the traditional sliming at the Nickelodeon Kids' Choice Awards in LA.
On stage to present the favourite movie actress award, the blue-wigged Perry was blasted in the face with the green gunk after opening the podium to find the winner's name inside.
While Miley Cyrus collected the statue, Perry was the centre of attention as she continued to entertain the crowd while covered in sticky goo.
The mystery sliming of celebrities has been a feature of the event since 1988.
