The news comes three weeks after O'Donnell announced she was separating from Rounds and leaving The View in order to focus on her children and on her health.
According to court documents filed with the Manhattan State Supreme Court on Friday, O'Donnell cites "an irrevocably broken relationship" as the reason for the divorce.
O'Donnell and Rounds wed in June 2012 and adopted a daughter, Dakota, a year later. O'Donnell has four older children with her first wife, Kelli Carpenter-O'Donnell.
