The ceremony, which was hosted by Will Smith, featured performances by Katy Perry and One Direction who performed their worldwide hit single, What Makes You Beautiful. The show, which celebrated its 25th anniversary last night and is run by the Nickelodeon cable TV network, is notable for the green slime that some winners are covered in.
Bieber was no exception when he won favourite male singer as voted by fans who also voted for the 18 year-old to get slimed. As he was being presented with the orange blimp trophy by Smith, green goo fell from the rafters but it accidentally splashed the US First Lady, Michelle Obama, who was seated in the front row.
Obama was present to give the "big help" blimp trophy to country star Taylor Swift. Swift "rocketed to the top of the music industry, but still keeps her feet on the ground," Obama said about the 22-year-old country singer, calling her "someone who is going to keep making sparks fly for all of us in the years ahead."
