The reveal came when Touch star Kiefer Sutherland was describing a 24 plotline in which the writers decided to make his costar Sarah Clarke a bad guy.

"That was my prom date, by the way," Hamm told a surprised Sutherland.

Clarke, who had a recurring 24 role as CTU-mole Nina Meyers, has more recently played Bella Swan’s mother, Renée, in the Twilight films.

“That's hysterical,” Sutherland said when learning of Hamm’s connection to Clarke. “I'm just trying to picture you dancing because she's quite a short girl.”

Hamm, who knew Clarke in their mutual hometown of St. Louis, Mo., replied that it “worked out fine.”
