Sheen's Ex: 6 ODs in 2 Years

We've known for a while now that Brooke Mueller is in a dark place, but Radar today reveals just how dark: Sources say that over the past two years, she's overdosed six times and has been hospitalized on every such occasion. And her current stint in rehab (at the Betty Ford Center, current home to Lindsay Lohan) is her twentieth. All of this was reportedly revealed to a judge during a hearing on the custody of Mueller's children; currently, Charlie Sheen's other ex-wife, Denise Richards, is watching them.

Brooke is "furious that Denise still has temporary custody of the boys," says another source. "She is insanely jealous of the relationship Denise has with the twins." But, says the first source, Mueller really should be focusing on her health: "It's amazing Brooke is still alive." Earlier this week, Sheen's legal team went to court to argue that the only reason Mueller is fighting Richards' custody is because she wants money, TMZ reports. According to Sheen, Mueller wants her brother to get guardianship of the twins so that Mueller will still have access to the $55,000 a month Sheen pays in child support. (More Charlie Sheen stories.)
