The family that plays together apparently stays together. Or vice versa. Consummate playboy Charlie Sheen must wield some wild and crazy power over his exes. How else can one explain the fact that Sheen's ex-wife (#2) Denise Richards helped him throw a birthday soiree for ex-wife (#3) Brooke Mueller? In fact, Richards even hosted the bash at her Beverly Hills home --and publicized it on Twitter. The irony of the entire situation was not lost on the former Bond girl who wrote, "Having a party 2day. Ex-wife #2(me) is having ex-wife #3(brooke) bday party at my house. Oh and our ex-husband will be here. How's your Sunday?" Of course, the guest list didn't feature any of the usual suspects with whom recovering addicts Charlie and Brooke usually partied. Instead it was definitely a family-friendly affair. A source told Radaronline.com, "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. 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." But don't expect the romance between Brooke and Charlie to be rekindled. The 35-year-old mother of two is currently hooking up with country singer Jaron Lowenstein. The handsome crooner is supposedly a good influence on Brooke. The insider tells Radaronline.com, "Jaron is from Nashville, and Brooke and the boys have been spending a lot of time with him in Tennessee. Brooke and Jaron are basically living together, and he is a great influence on Brooke, who has had issues over the years with substance abuse. Jaron isn't a party animal; in fact, he is the opposite of Charlie Sheen as he doesn't drink or even smoke."
