Holly Marie Combs, David Donoho file for divorce
Combs and Donoh met on the set of "Charmed" -- she played supernatural sister Piper Halliwell and Donoho was a member of the crew. They have three children together.
Irreconcilable differences were cited as the reason for the divorce in Combs' papers. A source tells TMZ that the couple's relationship has been "rocky for a while."
TMZ also claims the couple does not have a prenup in place.
