Hilary Duff files for divorce from estranged husband Mike Comrie

American singer/actress Hilary Duff has reportedly filed for divorce from her estranged husband Mike Comrie after separating from him for over a year.

The 27-year-old actress's decision comes after the Daily Mail reported that Mike was allegedly seen "drunkenly propositioning women" at a restaurant in Beverly Hills.

According to TMZ, Duff cited irreconcilable differences as the reason for the split, and listed the date of separation as January 2013.

Adding on, the former Disney actor is seeking primary physical custody of their son, Luca Cruz Comrie, who turns three next month, with the former NHL player having visitation rights.

Duff and Comrie who married in August 2010 had announced their "amicable separation" last year in January.

The Lizzie McGuire star, took to her Twitter account to address the split and tweeted: "Mike and I are sitting here, we are so appreciative for all of your kindness & well wishes. Not an easy day but we're getting thru it together."

Meanwhile, the Cinderella Story star's mother Susan Duff previously told TMZ that the break up was the only way the couple could remain friends.

"They're better friends than a married couple," she said.
