Rosie O'Donnell's daughter Chelsea O'Donnell has filed for divorce from her estranged husband.

The 20-year-old filed in Marinette County, Wisc., in April to end her marriage to Nick Alliegro, Rosie's rep confirmed Monday to People.

Us Weekly reported O'Donnell filed for divorce April 19, less than 22 months after she secretly married Alliegro in New York.

The couple first met at a Dunkin' Donuts in November 2015.

O'Donnell's new boyfriend, Jacob Bourassa, announced in a Facebook post in May that O'Donnell is pregnant with their first child.

"I'm so proud of you Chelsea O'Donnell your once in a life time find I feel like the luckiest man on earth you give me a reason to smile each and every day I look forward to are future together everything seems just right being with you your the greatest I love you," Bourassa wrote.

Rosie confirmed O'Donnell's pregnancy in a statement through her rep Saturday to People, saying she's reconnected with her daughter in light of the news.
