Charlie Sheen recently announced his engagement to girlfriend Brett Rossi but it looks like the two won't be walking down the aisle anytime soon because she's already married to another man. According to Radar Online, the porn star is currently in the process of divorcing her estranged husband, Jonathan Ross.

Ross filed for divorce on July 18, 2013 but Rossi didn't file a response until Jan. 30, 2014, according to court documents obtained by Radar. Ross will be representing himself in the proceedings while Rossi will be accompanied by Sheen's attorney, Mark Gross.

"The divorce between Brett and Jonathan is going to be finalized in the next few months, if not sooner," the source said. "There isn't anything that is being contested."

The two have been married for about a year and a half and didn't have any children together. Sheen has been married three times before and has five children. The "Anger Management" actor popped the question to Rossi on Valentine's Day while vacationing in Hawaii.

"In a moment of Kray-zee gratitude; I got my gal!! 4evurr!!" he tweeted on Feb. 14.

According to Radar, before Sheen and Rossi say "I do" they will be signing a prenup. A source told the site that the actor, who is worth an estimated $125 million, will be generous to Rossi in the legal document but wants to protect his assets.

"Once his current FX show, 'Anger Management,' goes into syndication, he will be earning even more money. The prenup will be very generous for Brett, but Charlie has to protect his finances even though he doesn't think the agreement will be needed, because he believes Brett is his soul mate," the source said.

"[Charlie will] pay for Brett's legal fees as they work out the details of the prenup," the source told Radar. "For him, this is only a formality. He doesn't think Brett is after his money. This time, it's different."
