(Cover) - EN Showbiz - Charlie Sheen feels he and ex-wife Brooke Mueller are on the path to "harmony".

The pair married in 2008, and they have two-year-old twins Bob and Max together, although their divorce was finalised in May this year.

Charlie and Brooke's relationship has been famously tumultuous, with past incidents including his arrest in 2009 at their home in Aspen, Colorado, for assaulting her.

However, the pair have been putting their differences aside for the sake of the kids, and TMZ has published a photograph of the former husband and wife smiling with Bob and Max. The snapshot was taken at the weekend at Charlie's Hollywood mansion, as Brooke had taken a break from her residential rehab programme.

Charlie told TMZ his tots had a wonderful weekend "playing around and scarfing down handfuls of candy".

"Harmony is our goal. Sunday was a wonderful start," he beamed.

According to the publication, Charlie is keen for Brooke to move into his neighbourhood once she completes her rehab programme as he wants to spend more time with his family.

Brooke has battled substance abuse problems for a long time, and received rehab treatment earlier this year. She was recently pictured carrying alleged drugs paraphernalia, and reports followed that she had checked into a residential rehab. It was later claimed that Charlie is paying for the programme. Apparently he had been keen to stop his ex-wife entering a rehab centre in Mexico where a controversial drug called Ibogaine is given to help treat addictions. (C) Cover Media
