Zac Efron, Megan Fox and New Hair

Zac Efron may be trying to move himself away from the teen hearthrob image to some a bit more serious. Is it the roles he wants - or, perhaps a new, sexy girlfriend, Megan Fox!

Zac has been spotted with Megan at a cozy dinner where a source told Celebuzz: "They were very friendly and their faces were close when they talked."

The San Francisco Chronicle also reported that Zac will be starring in a new thriller written by the same pen as the 'Thomas Crown Affair'.

'High School Musical' seems to have become just too innocent for him - even getting him to change his hair and his girlfriend.

Time will tell....
