Jennie Garth was admittedly heartbroken when her husband of 11 years, Peter Facinelli, filed for divorce in early 2012. But the actress and mother of three didn't mourn the breakup for long. The "Beverly Hills, 90210" alum lost 30 pounds of breakup weight, briefly dated a photographer, restocked her wardrobe with sexy red dresses, and showed her ex exactly what he was missing. Now the hot mama is a fixture on the red carpet, where she's frequently snapped strutting her stuff at Hollywood parties, charity events, and premieres. We guess single life isn't so bad after all!
