Holly Marie Combs - P 2011

The actress and her husband David Donoho met on the set of "Charmed."

Pretty Little Liars and Charmed star Holly Marie Combs has filed for divorce from husband David Donoho after seven years of marriage, TMZ reports.

Combs, 37, who is best known for playing witch Piper Halliwell on Charmed, married Donoho in 2004 after meeting on the set of the WB supernatural drama when he was a key grip on the show.

The actress cited irreconcilable differences as the cause for the separation and their relationship has been unstable for "quite a while."

Combs, who currently stars in ABC Family's Pretty Little Liars, and Donoho have three young children together and she is reportedly seeking joint custody. According to the report, there was no prenup. An active Twitter user, Combs has not yet commented on her split.
