Brooke Mueller certainly isn't winning!

Charlie Sheen's ex-wife and mother to his twin sons, Bob and Max, 4, was shot down in court again on Wednesday in her latest attempt to have Denise Richards stripped of temporary custody of the boys, Breaking Celebrity News is exclusively reporting.

The judge in child dependency court "flatly denied Mueller's request to to have Denise stripped of temporary custody, and placed in the care of her brother in Orange County. There was absolutely no reason that could justify the move, which would only uproot the twins yet again," a source told Radar.

"Brooke's claims that Denise was only taking care of the boys for financial gain fell flat because the actress signed a sworn declaration that she had refused money from Charlie. Denise's declaration also went on to say that she didn't want any money EVER for her care of the boys."

This is the second time in less than a week that Mueller tried to wrestle custody of the twins away from Richards. The judge denied her first request last Friday.
