Practical joker Justin Bieber and Taylor Swift have appeared in a commercial for the new series of hit MTV show, Punk'd.
Back in January 2011, reports had suggested that Biebs would be replacing previous host Ashton Kutcher to front the hidden camera show - which last hit TV screens in 2007.
Although the Never Say Never star is not a permanent replacement for Kutcher, Justin is among a number of celebrities who will present the prank show each week, starting from 29th March.
The new trailer for Punk'd shows Justin playing a joke on Swift - with the Safe & Sound singer concerned that she may have ruined a couple's wedding when a boat catches fire.
JB says in the clip: "I think we should start with Taylor, she's the sweetest girl ever", as Swift appears on screen looking concerned saying: "This is completely not OK!"
Although Kutcher may no longer be hosting Punk'd, the Two And A Half Men actor will act as the show's producer instead.
As well as Justin, the likes of Miley Cyrus, Jackass star Bam Margera and Twilight's Kellan Lutz will host the series, with Khloe Kardashian and Demi Lovato being Punk'd.
