Alesha Dixon has given an insight into what happens off-camera on Britain's Got Talent.
Ahead of the new series starting, Alesha says there's "never a dull moment" behind the scenes.
The singer will return alongside Simon Cowell, David Walliams and Amanda Holden for the 2018 series next month.
Alesha said: "Simon misbehaves. He’s 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."
Speaking to Star magazine, Alesha revealed how the panel took the tube to the auditions for one of this year's shows.
"Amanda and I were in our TV outfits and then we had David dancing around one of the poles, we were getting the strangest looks," she spilled.
Meanwhile, Alesha promised that the show was still continuing to find amazing new acts after 12 years.
"Usually we’re all a bit nervous about finding enough talent, but we were genuinely spoilt," she said. "Every year we can make a prediction about who’s going to win, but this year we couldn’t. "
Auditions for the new series of BGT wrapped up filming earlier this year.
As well as the usual singers and dancers there was also a plate smashing routine that ended in chaos and a moving performance from a victim of the Manchester Arena bombing.
Only a few hundred made it through after showing off their talents in front of this year's Britain's Got Talent judges.
Auditions for Britain’s Got Talent 2018 will start on TV from next month.
No air date has been revealed just yet, but rumour has it the show will begin on Saturday, April 14.
