Rounds and O'Donnell were engaged in a brief custody battle over their adopted daughter Dakoota, now 4, after Rounds initially filed for sole custody. In September of 2015, the former recruiter at Modis in New York City was hospitalized for an apparent overdose.

Rounds eventually got remarried to Krista Monteleone, who she was still married to when she died this week. She is also survived by her parents, Roger and Gayla Rounds, brother Tad Rounds, two daughters and a stepson.

Michelle's mother also released a statement mourning her daughters on Friday.

"If anyone would like to give to the National Suicide Prevention it would be greatly appreciated," she told TMZ. "There are so many out there in this world that have demons that they think suicide is the only way out."
