Charlie Sheen and Brett Rossi

Charlie Sheen and Brett Rossi

Charlie Sheen's got engaged earlier this month to his girlfriend Brett Rossi, but Charlie won’t be making his new fiancé his fourth wife anytime soon as she is already married. The Porn star is in the process of divorcing her spouse Jonathan Ross.

Jonathan filed for divorce on July 18 2013, but she didn't file a response until January 30 2014, two weeks before she got engaged to Charlie.

Brett - who had been married to Jonathan for a year - is being represented in the case by Charlie's lawyer Mark Gross, and insiders expect the proceedings to be resolved quite soon.

A source told RadarOnline.com: "The divorce between Brett and Jonathan is going to be finalised in the next few months, if not sooner. There isn't anything that is being contested."

Charlie - who already has grown-up daughter Cassandra with former girlfriend Paula Profitt, daughters Sam, nine, and Lola, eight, with second wife Denise Richards and twin sons Bob and Max, four, with former spouse Brooke Mueller - recently admitted he is "open" to having kids with his 24-year-old fiancee, but says they don't plan to do so just yet.

He said: "I'm having way too much fun with her right now. So much fun it should be illegal."

Charlie married for the first time in 1995, to Donna Peele, but they split a year later.
