Laurie Metcalf is about to return to the single life.
The Roseanne star, 56, who recently played Sheldon’s mother on The Big Bang Theory and her husband, actor Matt Roth, are splitting. Roth, 47, filed for divorce on Sept. 12 after six and a half years of marriage, citing irreconcilable differences.
The couple, who have been separated since November, 2008, have three minor children: Will, 17, Donovan, 11, and Mae, 6.
This was Metcalf’s second marriage and Roth is requesting joint physical and legal custody of the children.
