News: "I hope to do some more acting. I have only done a few things like 'CSI', but I really want to do some more acting."The 18-year-old heartthrob played troubled teen Jason McCann on two episodes of 'CSI' and most recently made a cameo appearance as an alien in 'Men In Black 3' alongside Will Smith and Tommy Lee Jones.The teen sensation - who is currently dating Disney star Selena Gomez - thinks his big break could come in the shape of a basketball movie he is planning with 'Ted' actor Mark Wahlberg.Justin said: "Mark Wahlberg and I - we've been working on the script for a long time now."Mark recently commented that Justin was the perfect choice for his upcoming film project, assuring critics that the pop star really "can act".He joked: "It's set in street hustling basketball... Obviously, [Justin] is a very good athlete. He can play. But I also really think he can act.""We're just going to have to make him realise that he's playing a character so he can't have the same hairdo."
