Melanie Lynskey, "Two and a Half Men" actress, files for divorce

It's over between "Two and a Half Men" actress Melanie Lynskey and husband Jimmi Simpson.

Lynskey, who plays Rose on the CBS sitcom, filed for divorce from Simpson, who stars on "It's Always Sunny in Philadelphia," last month, according to People.

The actress reportedly cited "irreconcilable differences" as the reason for the split. The couple had been married for five years.

Both actors waived the right to spousal support in the Sept. 25 filing in Los Angeles County Court, People reports. They separated on April 9, according to the court papers.

Lynskey and Simpson married on April 14, 2007. They have no children.
