Who is this fine looking man?

Now here's a face we haven't seen for awhile and damn, he's looking fine. He not only cleaned up his drug habit -- he was a slave to heroin -- but he's cleaned up his look, as well. He deserves an A+ on both counts.

The question is: who the hell is he? Is it Jason Mewes, the long haired druggie from indie hit "Clerks;" or Jesse McCartney, the former teen idol all grown up; or Corey Haims, an 80's movie star ready to make a comeback?

Take a guess and see if you know your d-list celebrities as well as you think you do.

And the answer is ...

It's Jason Mewes. The long locks are gone now that Mewes has opted for a cleaner lifestyle. He even spent six months in rehab back in 2003.

As for Jesse McCartney, he's never had a drug problem that we know of. The sexy young singer just released his latest album "Departure."

Then there is Corey Haims. He has struggled most of his life with drugs and alcohol, but he's also ready for a new lease on life. He will be reprising his role as Sam Emerson in "Lost Boys 2: The Tribe" and has a cameo in 2009's "Crank 2: High Voltage."
