Charlie Sheen's Ex, Brooke Mueller, Tries to Pawn Jewelry Just when we all thought the Charlie Sheen saga couldn't get more bizarre, the actor's estranged wife, Brooke Mueller, has upped the ante.

Mueller, the mother of Sheen's twin boys, Max and Bob, has been caught on camera trying to pawn a pricey watch and stereo equipment at an Inglewood, Calif. pawn shop in a desperate attempt to get some quick cash.

The 33-year-old actress, who checked into rehab for alleged drug and alcohol abuse issues in 2010, has reportedly been exhibiting behavior that has caused concern among her inner circle.

"Brooke seems depressed," Mueller's friend tells RadarOnline.com. "We're worried for her safety."
