Justin Bieber and his on/off girlfriend Selena Gomez were crowned the king and queen of the Radio Disney Awards on Saturday night (27Apr13) as they took home the event's top prizes.

The young stars, who called off their relationship last year (12) but recently reunited in Norway during Bieber's European tour, scooped Best Male Artist and Best Female Artist at the prizegiving in Los Angeles.

Gomez was able to pick up her trophy in person at the Nokia Theatre, but Bieber had to stay away as he continues his Believe shows, so he sent in a video message for his acceptance speech.

During the event, which celebrates the most popular recording artists among children and teenagers, Bieber and Gomez were pitched against each other in the Fiercest Fans category, but lost out to pop stars One Direction, who also won Best Music Group.

Taylor Swift was another big winner, taking home the Song Of The Year award for I Knew You Were Trouble and the Best Break Up Song prize for We Are Never Ever Getting Back Together.
