Get ready to watch the shit out of some television this fall, people, because Justin Mother-effin' Bieber is making his TV dramatic acting debut on CSI: Crime Scene Investigation! Says Deadline Hollywood:

Bieber will make his debut on CSI in the season premiere, playing "Jason McCann, a troubled teen who is faced with a terrible decision regarding his only brother—a decision that leads him into an explosive confrontation with the CSIs."

HEY! If Jon Hamm can be serious on Mad Men, and funny on Saturday Night Live, then Justin Bieber can be funny on Saturday Night Live and serious on CSI! Ahh, finally a reason to watch this show with my Grandma! (And by the way, Grandma, if you don't like it...)

Hat tips to Blogtown tipper Jack Gale!
