The guitarist in this yearbook photo is 52 now and he hasn't change that much, since his face is so similar. He was a looker then and continued to be one through his life as a major rock star in one of the most successful bands of the '80s. He was extremely popular with the ladies, wedding one super famous TV blonde and then went on to date Charlie Sheen's ex-wife.

His guitar playing, though, defined his New Jersey band's melodic hard rock.

He endured a stint in rehab last year, and even had to be replaced for a brief period on his band's tour, but he's back and better than ever.
