Last we heard, Christmas boozers, Charlie Sheen and Brooke Mueller were going to try and work things out. And the number of obstacles the couple are facing in maintaining their volatile marriage seems to increase as more information is unearthed about their relationship.

RadarOnline.com has spoken with an inside source that claims another skeleton in Brooke’s closet is that she attended rehab for alcohol abuse when she was five months pregnant with her and Charlie’s twin sons. According to this spy, it was when empty bottles of alcohol were discovered in her vehicle that she was confronted.

And when one of the boys was born with a heart condition, Charlie reportedly blamed his wife’s drinking. However, another source points out that this is a case of the pot calling the kettle black. The snitch explains, “They both have drinking problems. And neither of them should be drinking.”

A final source claims the two were doomed from the very beginning by saying, “The marriage has been bad since the beginning. It was just a matter of time before it exploded publicly.”

That source? Denise Richards. Ha! Kidding. I wish.
