After five years of marriage, it's over for Two and a Half Men
star Melanie Lynskey and her husband.
The actress filed for divorce from Jimmi Simpson, who stars on It's Always Sunny in Philadelphia
, last month.
Lynskey, who plays neighbor Rose on the CBS hit, cited "irreconcilable differences" in the Sept. 25 filing in Los Angeles County Superior Court. Both Lynskey and Simpson waived the right to spousal support.
The couple tied the knot on April 14, 2007. They separated on April 9 of this year, according to the court papers. They have no children.
Lynskey currently appears in the film The Perks of Being a Wallflower
