The funnyman appeared on Conan Thursday night and let the world know he's Team Robert Pattinson when he declared through his fake tears that Kristen is a "trampire!"
"I don't know if you follow the news at all, but there's this actress, Kristen Stewart, and she goes by K-Stew…she had a boyfriend, Robert Pattinson, and she cheated on him," Will jokes to Conan O'Brien.
Even though Kristen's indiscretions were with her Snow White and the Huntsman director Rupert Sanders, Will was more focused on the future of the Twilight franchise that Kristen and Rob star in together.
"They're broken up and they're not going to get back together, ever. And 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," he said.
"I don't know if there was anything I could have done to have prevented it. I don't know what it means to the Twilight franchise, I don't know!"
Will's skit is a spoof playing off British superfan Emma Clark, who uploaded a nearly 4-minute YouTube video with a Chris Crocker quality in which she calls Kristen a "hussy."
But Will one-ups Emma.
"She is a trampire!" he screams.
"That's what she is!"
