This chick’s flying the coop.
A rep for the Dixie Chicks musician tells PEOPLE the split is “a private family matter” and declined to comment. A rep for Pasdar did not immediately return request for comment.
A source tells TMZ the split is amicable.
The couple met in May 1999 at fellow Chick Emily Strayer’s wedding to her first husband Charlie Robison — Maguire was a bridesmaid, while the former Heroes star was a groomsman. A little more than a year later, they were married at A Little White Wedding Chapel in Las Vegas on June 24, 2000.
The Chicks — which include Maines and sisters Strayer and Martie Maguire — reunited in 2016 for a North American tour, capping off their return with a show-stopping performance featuring Beyoncé at the CMA Awards’ 50th anniversary in November.
