When Justin Bieber drops his [article id="1684318"]"Boyfriend" video this Thursday on MTV[/article], fans will catch a glimpse of a maturing Bieber. The 18-year-old star has moved on from the bowling party he threw in his "Baby" video to sun-drenched rooftop parties, with fast cars and one very seductive love interest he doesn't seem to mind snuggling up against.

The video's director, Director X, spoke to MTV News ahead of the premiere to tease a bit of what fans should expect from the video. He also dished about how he cast the video's lucky leading lady. "You know you're casting a beautiful girl. It's the way the chips fell," he explained of the exotic brunette who bears a striking resemblance to Bieber's real-life girlfriend, Selena Gomez. "You know, I guess Justin has a type that he likes, so hey, you know, there you go."

As for the maturity of the video, he said that it's a reflection of where Bieber is at these days as he transitions out of his tweeny bopper days and looks to more adult pastures. "He's 18 now. He can drive a car. You grow into manhood. He's growing into his manhood so this is something where we really feel like we're seeing him grow," he said. "It's not the same old Justin."

The video was [article id="1683642"]shot in Los Angeles[/article] in late March. "Boyfriend" is the lead single off [article id="1684292"]Believe,[/article] out this June.
