Charlie Sheen, estranged wife Brooke Mueller aim for harmony

Actor Charlie Sheen met his estranged wife Brooke Mueller in a bid to improve their relationship for the sake of their children.

Sheen split from Mueller after an altercation in 2009. They subsequently went through a custody battle over their twins, Bob and Max.

But Sheen proved he is eager to rebuild their family after inviting Mueller to his Hollywood Hills home to spend the day with the boys.

"Harmony is our goal. Sunday was a wonderful start," Tmz.com quoted the 45-year-old actor as saying.
