Ashton Kutcher will be back as a producer, but not as the host when "Punk'd" returns to MTV on March 19.
Instead, new episodes of the reality series Kutcher co-created will be introduced each week by a different celebrity. Justin Bieber, Miley Cyrus, Kellan Lutz, Bam Margera and former "Punk'd" cast member Dax Shepard will be among the guest hosts when the show returns.
Check out a sneak peek of the new episodes below, as Khloe Kardashian gets "Punk'd" with a medical emergency reminiscent of "There's Something About Mary":
