Ty Pennington

This former model got his big showbiz break during his carpenter day job, when he was tapped to join the crew of the home-improvement cable series Trading Spaces in 2000. Three years later, this zany handyman earned his own network show, Extreme Makeover: Home Edition, which allowed him to shout through a bullhorn, knock down walls and tear up at the sob stories of the families he helped. Pennington's good looks and goofy antics endeared him to audiences and even led to a handful of acting gigs. Off screen, Pennington has designed his own furniture line, played in a one-man band named Barney and authored a how-to book. In May 2007, he tarnished his good-guy image when he was arrested for driving while intoxicated.
