Bieber best male at Kids' Awards -- and top choice to get slimed

THE green slime flowed so much that even US first lady Michelle Obama could not escape it at the Kids' Choice Awards on Saturday, where singers Justin Bieber and Taylor Swift were the big winners.

The programme is an annual stop for Hollywood stars who are popular among teenage and young viewers watching the Nickelodeon cable TV network, and this 25th anniversary was no exception.

Hosted by Men In Black movie star Will Smith, the awards featured performances by Katy Perry and British boy band One Direction.

But, as always, the green slime was the biggest star at the show, where Bieber won favourite male singer in fan voting.

On stage, Bieber took the orange blimp trophy from Smith, then the show's host had a surprise for the 18-year-old pop star. Bieber was also voted by fans as the celebrity they most wanted to see get slimed, and the green goo flowed from the rafters and water cannons aimed at the stage.

There was so much goo splashing around in the finale that it splattered on the face of a surprised first lady.

Michelle Obama was on hand at the popular show to give the "big help" blimp trophy to country star Swift.

The honour, bestowed on Obama two years earlier for her work with kids' fitness and health, goes to a celebrity who has devoted time and energy to charitable causes. Swift was singled out for her work to stop bullying and for providing aid to tornado victims in the southern United States.

Selena Gomez (19) was named favourite female singer for her work with pop band The Scene, as well as favourite TV actress in the Wizards Of Waverly Place.
