The Madness Never Stops! Charlie Sheen and his Ex Wife Denise Richards Throw a Party for his Third Wife Brooke Mueller

Charlie Sheen and his ex wife Denise Richards have thrown a birthday party for his third wife Brooke Mueller last night.

According to Radar Online, the former couple planned the party for Brooke together even though Charlie and she are no longer an item.

"Charlie and Denise decided to throw Brooke a birthday party in honor of her 35th birthday. Charlie's kids with Denise, Sam and Lola, and his kids with Brooke, twins, Bob and Max, along with Richards' adopted daughter, Eloise will be in attendance," a source said.

Although Charlie’s romantic relationships with the women didn’t work out, it has been reported that the three are good friends despite their past spats.

"Charlie, Denise, and Brooke all get along extremely well. They want what is best for their kids, and truly love and support each other. Brooke is looking ahead to an exciting year, and is dedicated more than ever to being the best mom she can to Bob and Max, and knowing she has the support of Charlie and Denise truly means so much to her," the source said.

Denise and Charlie have had a turbulent relationship and last year viciously fought for custody of their two daughters Sam and Lola.
