Kristen Stewart was a guest on The Tonight Show with Conan on April 8, and she had a thing or two to say about pulling off a Justin Bieber impression.

The Beebs has already been burnt enough, considering he just went through a Comedy Central Roast, but fellow celebrities aren't quite done with him yet. Conan O'Brien talked to Stewart about her participating in the music video for Jenny Lewis's song 'Just One of the Guys.' In the video, Stewart played the part of a dude, something of a jock, with a moustache and donning a pair of track pants. Conan asked Stewart if she was trying to channel Bieber while doing the part, to which Stewart had took a mild swipe at the pop star saying, "in his dreams." But she quickly went on to check her self, although still laughing: "I didn't even mean that! That was like, such a cheap, stupid joke."

She also revealed that Jenny Lewis was one of her favorite artists, as was the band Rilo Kiley, and that she was just glad to be part of the video in anyway.

The actress also spoke about being nervous meeting Robert Redford at the Sundance Film Festival where her film Camp X-Ray premiered.

Stewart's latest film, Clouds of Sils Maria, which also stars Juliette Binoche and Chloe Moretz, hits theaters on April 10. Stewart recently won the César Award for best supporting actress for her role in the film.
