Justin Bieber Opens Up About His Return To 'CSI'

'I'm not a bad person, so it's funny to play a bad person,' pop star says of reprising role of troubled teen Jason McCann.

Beliebers, get ready for another dose of [artist id="3187077"]Justin Bieber[/artist] as mischievous Jason McCann on a second episode of "CSI," which airs Thursday on CBS. In a behind-the-scenes video, the "Never Say Never" singer discusses his return to the crime series, reaction to his first episode and his dream acting role with Will Ferrell.

As teased in January, Bieber's character is back to his old habits as he continues on a dangerous and downward spiral. "It started in the first one where I bombed a funeral. Yeah, it sounds bad, but I bombed a funeral," he says of his debut episode. And it doesn't stop there, as the Biebs reveals that his character continues a bombing scheme in the follow-up cameo.

Asked why the singer chose "CSI" for his acting debut last September, JB admitted he's a fan and ultimately wanted to choose a role that would test his acting skills. "First of all, I think it's a really cool show. I like the show myself," the star said. "I wanted to do something that's going to be challenging for me, and it's definitely going to be. It has been."

In between his commentary, clips of the episode are shown, including one where a bruised Bieber is reunited with Nick Stokes (George Eads) and the "CSI" team member tells the youngster that he'll protect him despite the circumstances.

While the pop star is known for his swooping hair and adolescent charm, Bieber enjoyed his role as the troubled McCann, saying, "I'm not a bad person, so it's funny to play a bad person." And he wasn't the only one, as the star said his family was "really excited" to watch his first stint on the show, including his grandpa, who is an avid fan of all the "CSI" spin-offs. "He was really happy to see me and it was really fun," the singer said.

Bieber may not be around to live another day on the CBS series, so what dream role would he like to flex his acting chops on next? "To do a comedy with Will Ferrell like play his son or something like that," a grinning Bieber said, adding, "What's up, Will?"
