Hmmmm, kind of throws a spanner in the marital works, but - hey - at least it won't stop them having kids... yaaaaaaaaay. He hasn't nearly got enough of those.

The Anger Management "actor" got engaged to Brett Rossi earlier this month but he won't be able to make her his fourth wife for some time as she is in the process of divorcing her spouse Jonathan Ross. I know, who knew?

Jonathan - who is representing himself in the proceedings - filed for divorce from the porn star on July 18th last year, but she didn't file a response until January 30th just gone, 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 (seriously), and insiders expect the proceedings to be resolved quite speedily.

A source told RadarOnline: "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." It invariably is.
