Bradley Copper claims that there is no truth to reports that he may play Lance Armstrong in an upcoming biopic about the wayward Olympic cycler.

Just one week prior, the actor supposedly expressed interest in playing the role of Armstrong, if there were to be a film about his life.

"I would be interested in that,” he told the BBC on Jan. 22. "I think he's fascinating. What a fascinating character."

"I remember Matt Damon was going to do his autobiography at one point years ago,” he continued.

"I remember thinking that would be a great character; I'd love to play that character. I would love to do something; I think he's pretty fascinating."

Now that director, JJ Abrams has now come forward saying that he has been in talks with Cooper about possibly playing Armstrong in an a book based film that he recently received the rights for, the “Silver Linings Playbook” star now claims that his words were misinterpreted.

Access Hollywood spoke to Cooper on the red carpet at the SAG Awards on Sunday and inquired about his involvement with the Lance Armstrong film.

“No,” he said with a “massive” laugh. “Oh my God, that’s so nuts!”

“I was in Manchester, doing the BBC morning show … I had no idea what [the interviewer] was talking about,” Cooper explained to Access Hollywood’s Shaun Robinson. “I didn’t even know that J.J. has the rights, I had no idea.”

Paramount Pictures and JJ Abrams' production company Bad Robot have in fact recently acquired the rights to a book proposal by Juliet Macur called “Cycle of Lies: The Fall of Lance Armstrong.”

Macur commissioned the book in mid-January just after Armstrong publicly admitted to using performance enhancing drugs during all seven of his Tour de France wins, according to Entertainment Tonight.

Abrams spoke with ET backstage at the Producers Guild Awards on Saturday and said confirmed that Cooper was in the running for the role of Armstrong.

"[Cooper] sent me an email and we've been talking," he told ET's Christina McLarty.
