Fifteen months after we first reported that MTV is bringing back celebrity hidden-camera series Punk’d, the cable network today acknowledged the series’ existence for the first time. While MTV confirmed that Katalyst’s Jason Goldberg and Ashton Kutcher — the masterminds behind the original series that ended its run in 2007 — are back as executive producers, the network stopped short of announcing any involvement of pop star Justin Bieber, who had been attached to the reboot. MTV will introduce the new Punk’d with a sneak peek during its New Year’s eve show, NYE in NYC 2012 on December 31, when MTV plans to reveal details about the reboot — including host(s).
