‘Will & Grace’ Star Eric McCormack’s Wife Files For Divorce

Eric McCormack‘s wife is pulling the plug on their union after more than two decades together … because she just filed for divorce.

Hollywood director Janet Holden beelined it to court Wednesday and filed to divorce the “Will & Grace” star after more than 26 years of marriage.

According to new legal docs, obtained by TMZ, Janet is going with the boilerplate “irreconcilable differences” as the reason for the split … and she does not list a date of separation.

Janet is seeking spousal support … and she wants to end the court’s ability to award Eric spousal support. They do not have any minor children together … as their only son is 21 years old.

Eric and Janet first met in 1994 on the set of the “Lonesome Dove” TV show … where he was an actor and she was the assistant director. They got hitched in August 1997.
