Canadian pop star and teen sensation Justin Bieber has joined the cast of 24, playing an ambitious young CTU Field Agent who will partner with Jack Bauer (Kiefer Sutherland) in the final two episodes.
“Justin is nothing short of a phenomenon,” says “24″ executive producer and showrunner, Howard Gordon. “It’s so rare to find an artist this young with such pure star quality and dynamic presence. This is an exciting time for Justin Bieber fans, for the 24 family, and for television in general.”
“Bieber Fever has taken over with 150 million views on YouTube and total domination of Twitter trending topics for months. This series finale will be the most talked about television event of the decade thanks to Bieber’s star power,’” Fox TV spokesman Chris Alexander added.
24 has traditionally cast Canadian actors including Elisha Cuthbert, Leslie Hope, Carlo Rota, and Colm Feore as First Gentleman Henry Taylor. The series star, Kiefer Sutherland, and it’s directors Brad Turner and Milan Cheylov are also Canadian.

DISCLAIMER: THIS WAS AN APRIL FOOLS DAY JOKE. IT’S NOT REAL. Thanks to all of those who played along and retweeted etc (and sorry for those that got fooled – be glad it’s not real!). And for the guy who emailed me, yes I do feel a little dirty for having researched Bieber.

On March 22, 2010, Assaf will Guest Star as a murder suspect on CSI: MIAMI. Two weeks later, on April 5th, Assaf returns to FOX’s “24″ as a bad guy!
