Alesha Dixon says Simon Cowell is the most mischievous "Britain's Got Talent" judge.
The 39-year-old star sits on the panel with Simon, David Walliams and Amanda Holden and Alesha has revealed that it is the 58-year-old boss who spends a lot of his time trying to prank his colleagues.
Alesha admits the atmosphere on set is akin to being back at school, with Simon acting up as the jester.
Speaking to the new issue of Star magazine, she spilled: "Simon is quite mischievous and he's always on the wind-up. There's never a dull moment because he's always looking for that little thing that's going to make you laugh or trip you up. It's like being back at school. He tries to draw you into his strange world."
Of her three co-stars Alesha admits she gets on with Amanda best and she thinks she's the only judge she could handle being trapped in a lift with.
When asked which of her "BGT" colleagues she would want to be stuck in a lift with, she answered: "Amanda. If you're in a situation like, you want to be with one of your girls. We would have a lot to talk about and if it got to hot we'd be able to strip off."
Alesha can't wait for "BGT" to be back on ITV and she says that she and the other judges were blown away by the quality of the acts this year.
She said: "Usually we're all a bit nervous about finding enough talent, but we were genuinely spoilt. Every year we can make a prediction about who is going to win, but this year we couldn't."
