Brooke Mueller reportedly allowed Charlie Sheen to spend time with his sons yesterday (14.01.14).

The troubled former actress - who has been locked in a bitter custody war with Charlie - let the 'Anger Management' star and his new girlfriend Brett Rossi spend two hours with four-year-old twins Bob and Max last night at his house in California.

A source told RadarOnline: ''Brooke allowed Bob and Max to go over to Charlie's house on Tuesday night for two hours. Charlie introduced Brett to the boys and he was very impressed with how maternal she was, even though she has no kids of her own.''

The 36-year-old ex-model - who has been to rehab 20 times - lost custody of the twins in May when she was put under involuntary psychiatric hold, stemming from a drug overdose.

The twins were being looked after by another of Charlie's ex-wives, Denise Richards, until they displayed violent behaviour to her own children, and were placed in the care of Brooke's brother, Scott Mueller.

The source added: ''When the allocated time was up, the boys were turned back over to Brooke's brother, Scott, who has temporary guardianship of Bob and Max.

''Brooke wasn't present for the visit because she has a restraining order against Charlie.''

However, a monitor was present for the entire visit.

Charlie, 48 - who married Brooke in 2008 before divorcing her in 2011 - reportedly hasn't seen Bob and Max since before Christmas.

He also has a grown-up daughter Cassandra from a previous relationship and daughters Sam, nine, and Lola, eight, with Denise.
