Los Angeles: At last troubled actor Charlie Sheen's divorce from Brooke Mueller has been finalized.

The first rupture in their relation hit headlines in 2009 when Charlie was arrested on Christmas Day following a bust-up with his wife

The 45-year-old actor subsequently pleaded guilty to a charge of misdemeanour assault and was handed a suspended jail term.

The couple split, and Mueller, mother of the Sheen's twin sons, filed for divorce in January last year, which was finalised on Monday after the former couple reached a settlement agreement.

The former 'Two and a Half Men' star will pay Mueller USD 55,000 a month in child support for Bob and Max, two, as well as a lump sum of USD 757,698.

Sheen has been allowed to keep the family home in Los Angeles, but will reportedly pay Mueller USD 1 million for her share of the property.
