Will Ferrell has once again made light of Kristen Stewart's affair with Snow White and the Hunstman director Rupert Sanders.

Earlier this week the actor jokingly declared that he 'doesn't care what's going on in Syria' in the wake of Stewart and Robert Pattinson's shattered relationship.

Ferrell further joked about the scandal as a guest on US TV chat show Conan, when he mimicked a viral video of Twilight fan Emma 'Nutty Madam' Clark sobbing over Stewart's infidelity.

"I don't know if you follow the news at all, but there's this actress Kristen Stewart – she goes by K-Stew - and she had a boyfriend Robert Pattinson – he's R-Patz," Ferrell explained to Conan O'Brien.

"And she cheated on him! And they're broken up! They're not going to get back together . . . ever!"

Ferrell then began weeping and shouted: "What they had was so special, Conan! You don't even know what they had! They were in love and she just threw it all away!"

Pretending to get angry, Ferrell added: "She is a trampire! That's what she is."
