Charlie Sheen Calls Brooke Mueller’s Claims a ‘Friggin’ Lie’

Mueller, 33, says in a sworn statement filed Tuesday in Los Angeles court that her ex-husband once referred to his manager, Mark Burg, as a “stoopid Jew pig,” which Sheen disputes, saying that Mueller manipulated text messages on his phone.

“I would never, ever say that about my dear friend Mark. [Mueller] is trying to create discord,” Sheen, 45, told PEOPLE Wednesday. “I caught her on my phone a year ago texting. She was trying to cause discord among my immediate family. I caught her red-handed and she confessed.”

“This is no different,” he adds. “Natty and Rachel (aka “the goddesses”) observed her on several occasions [recently] with my unlocked phone that I should never have left out.”
