Taylor Swift might have let Justin Bieber crash her Tuesday night (August 23) concert in Los Angeles, but she may not want to share a stage with him now…

According to Access Hollywood, the 21-year-old songwriter was pranked by the 17-year-old “Baby” singer.

A source told the outlet that the prank happened on Friday (August 26) for MTV’s revival of Punk’d.

In the show’s revamped format, creator Ashton Kutcher is just a exec producer and will host different celebrities pulling pranks on their friends and random, unknowing targets.
