Kiefer: "I Really Regret" Headbutting Incident (VIDEO)

Kiefer Sutherland joined Jimmy Fallon Thursday night, and Jimmy joked about the Met gala a few weeks ago that ended with Kiefer charged with assault for allegedly headbutting designer Jack McCollough and breaking his nose.

"The last time I saw you, we went out to dinner and then ... what happens?" Jimmy asked the "24" star. "I just want to know, how close was I from being on the receiving end?"

"Not even close," Kiefer assured him. "Unfortunately, we can joke about it, I guess, but it's something I really regret having happened, and until it's resolved I can't talk about it."

Jimmy followed that with, "Do you think you're [24 character] Jack Bauer?"

"Absolutely not, absolutely not," Kiefer responded. "I learned that really clearly the first season."
