Justin Bieber, ‘Watch Your Back’: Carly Rae Jepsen Loves Pranks Too!

'I'm going to give him a run for his money,' Bieber protégé tells MTV News of recent 'Punk'd' mastermind.

“Punk’d” kicked off in a big way Thursday night. Justin Bieber was enlisted to host the premiere episode of the new season, and he didn’t shy away from pulling fast ones on his A-list friends.

Bieber made Taylor Swift believe she ruined a wedding, leaving her in tears. And when he pranked MTV’s own Rob Dyrdek, he caught on and ended up joining forces with the Biebs to get Sean Kingston instead; the stunned singer stood up for an angry assistant who drove her boss’ car into a restaurant. Bieber also double-crossed Miley Cyrus, who thought she was pranking him, but he ended up fighting the kids she sent out to poke fun of him. She definitely wasn’t expecting that and ended up pretty shocked by the reverse prank.

Bieber is a known prankster in real life, and his pal and label signee Carly Rae Jepsen opened up to MTV News about his punker side — and proudly said she’s ready to take him on anytime.

“I haven’t seen that side of him myself yet, but I heard he’s a bit of a prankster, which is good. I like that,” she told MTV News. “I’m going to give him a run for his money. I enjoy a prank or two myself. It’s on! Watch your back!”

Cyrus will be back for more “Punk’d” fun later this season, when she hosts her own episode. She’ll punk beau Liam Hemsworth and pal Khloé Kardashian. Demi Lovato, the Wanted and more will also get “Punk’d” later this season.

Don’t miss “Punk’d” every Thursday at 10 p.m. on MTV. For continuing “Punk’d” coverage, be sure to check in with MTV’s Remote Control blog.
