Most famous role: Buffy Summers in Buffy the Vampire Slayer (1992)

Forget Sarah Michelle Gellar: Kristy Swanson was the original vampire-hunting Valley Girl in the big-screen version of Buffy the Vampire Slayer. The two decades since have been less hectic for Swanson; her most prominent role may be the one she played in breaking up the marriage of Lloyd Eisler, her partner on the 2006 reality series Skating With Celebrities. Swanson began a relationship with Eisler, whose wife at the time was pregnant. (Swanson and Eisler had their own son in 2007, a month after his divorce was finalized; and they married in 2009).
