The break up of 'Twilight' stars Kristen Stewart and Robert Pattinson has turned Hollywood completely upside down, and it looks to have affected Will Ferrell the most.

Stewart (Bella) cheated on her on- and off-screen beau Pattinson (Edward). Stewart had an affair with her married director of her latest film "Snow White and the Huntsman." Word (and pictures) of the affair quickly spread, causing her to speak out, admit the affair and apologize.

Stewart and the director Rupert Sanders are the only people involved who have publicly acknowledged the affair. Everyone in Hollywood is keeping pretty mum on the affair. Fans across the world have made it very clear that they are heartbroken and angry at K-Stew for breaking the heart of Rob Pattinson.

Among those fans is funny man Will Ferrell. Will stopped by 'Conan' to promote his new comedy "The Campaign." During the interview Will got very somber and upset, prompting Conan to ask what was wrong. Will admitted his heartbreak over the Edward-Bella breakup.

He is showing the true emotion of Twi-Hards everywhere.
