Charlie Sheen 'teaching kids about Mueller rehab'

Charlie Sheen has claimed that he will teach his children about their mother Brooke Mueller's drug and alcohol problems.

The former Two and a Half Men star gained access to 2-year-old twins Bob and Max this weekend after Mueller checked into rehab last month.

Speaking to TMZ, Sheen explained that he was hoping to use the time to educate his children on their mother's current whereabouts.

He stated: "I am teaching them words, because they're speaking now. I'm teaching them the word 'rehab' so they always know where their mum is."

Sheen recently lost a bid to gain full custody of the boys, after Mueller violated the terms of their agreement by refusing to take a random drug test.

Sheen and Mueller married in 2008 and separated in 2010. Their divorce was finalised earlier this week. The former couple welcomed Bob and Max in March 2009.
