Before They Were Famous: Matt LeBlanc
This is almost a two-fer.
Before Alanis Morrissette went all angsty on us with 'Jagged Little Pill,' she was a bubbly Canadian pop star. And in her video for the single 'Walk Away,' a youthful Matt LeBlanc -- with a delicious head of '90s hair -- plays her boyfriend.
By the time the clip was released in 1991, he'd already had a role as Kelly Bundy's boyfriend Vinnie Verducci on 'Married... With Children,' a part that crossed over to two other shows. But he didn't hit it big until three years later, when a little sitcom called 'Friends' made him a household name.
