O'Donnell responded to the criticism on Twitter by revealing that Rounds "gave up her custodial rights" as part of their 2015 custody battle. While Rounds technically didn't have custody of Dakota, she still spent time with her daughter with O'Donnell's permission.
Police found Rounds' body earlier this week, and the news of her death was announced Friday. Rounds had previously attempted to take her own life soon after her split with O'Donnell. The couple were married for two years before divorcing. O'Donnell shared that she was "saddened" by Rounds' passing.
