“Were you channeling who I think you were channeling?” Conan O’Brien asked. “It very much felt like you were doing a sort of Justin Bieber … minus the mustache.”
“In his dreams,” Stewart, who turned 25 Thursday, responded, before blushing slightly. “I didn’t even mean that! I don’t know where that came from. That was such a cheap, stupid joke.”
Stewart says she’s an “obsessive fan” of Lewis’, and could barely hold it together when she met the former Rilo Kiley frontwoman and actress for the first time.
You can currently catch Stewart alongside Juliette Binoche in Clouds of Sils Maria, in theaters Friday.
