Two And A Half Men star Melanie Lynskey is single again after finalising her divorce from actor Jimmi Simpson.

The actress, who plays Rose in the hit sitcom, split from It's Always Sunny in Philadelphia star Simpson in 2012 and now the union has been officially dissolved, according to Tmz.com.

The website's editors report the divorce was amicable and was conducted without lawyers. The former couple agreed to split its assets fairly and not to pay each other spousal support.
