Alesha Dixon was forced to change her hotel room last week when Britain's Got Talent co-judges Simon Cowell and David Walliams revealed her room number to a budding rapper on the show.

During the recent auditions in Wales, Simon and David were apparently in a mischievous mood and reportedly saw their perfect target when a rapper appeared on stage and tried to set him up with single Alesha.

"You could see that Simon and David were being mischievous," the source told The Sun.

"It was like they wanted to make a point about Alesha being single. But this guy was definitely not Alesha's type."

Simon told the contestant: "Alesha's staying at St David's Hotel - room 511," before David added: "She will be back there and waiting for you at about midnight."

Clearly not impressed with the duo's match-making skills, Alesha shot back: "This isn't Blind Date. I'm here to judge talent, not find it for myself. Alesha couldn't believe they had disclosed where she was staying. She had to change her hotel room as soon as filming finished for the day."
