O’Donnell also took to Twitter Friday to retweet a fan who expressed their condolences and shared a suicide prevention hotline number: “lovelovelove to @Rosie. If this is triggering anyone, I hope they’ll contact the suicide prevention hotline 1-800-273-8255.”

The Orange County Sheriff’s Office told The Blast that Rounds’ body was found at 7:07 a.m. on Sept. 11. TMZ first reported the news.

Rounds was born in Corning, New York, on May 10, 1971 to Roger and Gayla Rounds and later attended college at State University of New York. She went on to become a top recruiter for Modis in New York City, according to her Carpenters Funeral Home obituary. She was hospitalized for an apparent overdose in September 2015.

The former couple wed quietly in June of 2012 at their home in Nyack, New York. The comedian filed for divorce from Rounds in February 2015, and the two reached a settlement in October 2015. At the time, O’Donnell told reporters both women were “very happy about the outcome.”

The exes, who were married for just over two years, previously battled for custody of Dakota after Rounds filed for sole custody in April 2015. They finalized their divorce in March 2016.

Rounds is survived by her wife, Krista Monteleone; parents Roger and Gayla Rounds; brother Tad (Janet) Rounds; two daughters; and one stepson. Her family will hold a private memorial service.
