Will Ferrell Mourns Kristen Stewart & Robert Pattinson's Break-Up On 'Conan' (VIDEO)

Will Ferrell got emotional on Thursday night's "Conan," but it had nothing to do with the movie he was there to promote.

Mid-interview, the "Campaign" star broke down into tears over "Twilight" stars Kristen Stewart and Robert Pattinson's recently-rocky relationship. If those two can't find the perfect love, who can, man?

So if you were hoping for another clip of Ferrell and Zach Galifianakis being zany, you're out of luck, but if you're still working through your own complex emotions surrounding celebrity news, this is the right interview for you.

Just hit play.

Shhh.
