Charlie Sheen and Brooke Mueller threw a birthday party for their twins Bob and Max on Saturday (15.03.14).

The pair - who have been locked in a bitter custody war about their children - put their differences aside to plan the bash, which took place the day after the boys' 5th birthday.

Charlie's fiancée Brett Rossi - who also helped them work out plans for the celebrations - was also present at 'Anger Management' star's house for the party, gossip website TMZ reports.

The celebrations come after Brooke - who originally lost custody of the twins when she was placed on involuntary psychiatric hold at the UCLA Medical Center last year - moved back into the Mulholland Estates house the 48-year-old actor bought her.

The 36-year-old star is now taking care of her sons, rather than her brother, Scott, who was appointed their guardian before Christmas.

A source said: ''Brooke has been living at the mansion in Mulholland Estates since before Christmas.

''The boys had been living at the house with their temporary guardian, Scott Mueller, but he hasn't been spotted at the house lately.

''He's been back at his house in Orange County [California] to be with his family. Brooke does have a nanny and a sober living companion also with her in the house. There just wasn't enough room at the condominium she had been living at for her staff.''

Before Scott took custody of the boys, they had been looked after by another of Charlie's ex-wives, Denise Richards.

However, last November she relinquished care of the twins as she worried their violent behaviour was putting her daughters Sam, 10, Lola, eight, and Eloise, two, in danger.
