This Emmy-winning star is also half of one of Hollywood's cutest couples. But who is it? In the latest installment of "Celebrity Face-Off!" Rachael challenges two audience members to name this actress as her face is slowly revealed. It's a tense game and the "contestants" identify Sarah Michelle Gellar just as her entire face appears. "That was really tough!" Rachael says before calling it a tie and allowing the audience members to split the lunch for two at the Palm Too steakhouse.

Gellar joins them all on stage and then heads to the kitchen table to tell Rach about her charitable work with CARE.

See why Gellar's so passionate about this charity in this backstage interview!
