To the suprise of absolutely no one, Zac Efron has been exposed as a closet-case — although not quite the kind you had in mind.

Tattles close to the 17 Again cutie tell The National Enquirer that the dashing young actor is harboring a secret fixation with cancer sticks that he is desperate to keep out of the public eye.

The Enquirer claims: The teen heartthrob enjoys an occasional smoke, but he’s super-conscious of his young, impressionable fans and doesn’t want to send the wrong message, so he sne-e-e-eaks – smoking behind closed doors only, or in the privacy of his home.
