Debra Messing and her husband, Daniel Zelman, have parted ways.
The pair, who are parents to 7½-year-old son Roman, “privately separated earlier this year after a 10 year marriage,” Messing’s rep confirms to PEOPLE.
“The decision was mutual, and they remain supportive of one another and committed to raising their son as a family.”
Messing, 43, first met Zelman – now an actor and producer – when they were both students at New York University (and then dated for eight years).
