Ludacris 'trapped in elevator before Leno'

Ludacris was almost forced to cancel a guest appearance on talkshow The Jay Leno Show after getting stuck in an elevator.

According to Contactmusic, the rapper was convinced that last night's incident had been orchestrated by Ashton Kutcher's MTV show Punk'd.

Ludacris later told presenter Leno: "I almost didn't make it. We got stuck in the elevator and I thought I was being punk'd!

"Luckily that's not the case. It was only for about four minutes, so I'm good."
