Baby Mama Drama: Charlie Sheen’s Exes Think He’s Hiding Cash!

Denise Richards and Brooke Mueller weren't surprised their when mutual ex-husband, Charlie Sheen, filed court documents asking for a reduction in monthly child support payments — and believe the former Two and a Half Men star is hiding cold hard cash in his Rosarito, Mexico home, RadarOnline.com can exclusively report.

The exes agree "Charlie isn't making any money, but they think he still has a lot of assets, including his Mulholland Estates mansion, which he is trying to rent out for $43,000 a month,” a source told RadarOnline.com. “He also has an extensive watch collection, baseball memorabilia and cold hard cash which is being stashed at his Rosarito home.”

Sheen’s two baby mamas have heard the house suddenly has armed guards in front of it, which they believe is suspicious because Sheen doesn't stay there often.

Now, “Brooke and Denise are going to fight any attempt to lower the child support payments.

As RadarOnline.com previously reported, Sheen claimed in new court documents this week that he’s been “blacklisted” in Hollywood and can no longer find work — so therefore he can no longer afford his monthly $20,000 payment to Richards, the mother of his daughters Sam, 14, and Lola, 13, and $55,000 monthly payment to Mueller, the mother of his 9-year-old twin sons Max and Bob.

Sheen, 52, said he had less than $10 million to his name, a far cry from the height of his TV days, when he was pulling in nearly $2 million an episode for his top-rated show.

Richards, 47, split from Sheen while she was pregnant with Lola in 2005 after three years of marriage. They underwent a nasty divorce, and have shared and up and down relationship ever since.

Mueller, 40, divorced Sheen in 2011 after three years of marriage.
