Rosie O'Donnell's 17-year-old daughter Chelsea O'Donnell has been reported missing.

Rosie revealed the devastating news on her website earlier today with a post titled "CHELSEA O'DONNELL MISSING." The 53-year-old TV host is extremely concerned for her daughter's health.

"Rosie O'Donnell's 17 year old daughter, Chelsea O'Donnell was reported missing," the statement reads. "Nyack, New York police authorities have been looking for her in the Rockland County area since Sunday, August 16. She was last seen Tuesday, August 11. She was wearing a black sweatshirt hoodie, dark ripped blue jeans, women's grey converse sneakers and a black backpack. Chelsea has a large tattoo on her right side of a dream catcher with the word 'Breathe.' She left home with her 6 month old therapy dog named Bear. The dog is a 9 lbs brown and black terrier. Chelsea stopped taking her medicine and is in need of medical attention."

Rosie took to Twitter to continue spreading the heartbreaking news. "Chelsea and her dog bear - last seen in nyack ny - may be in NYC," she wrote alongside a photo of the dog and Chelsea.

"Chelsea, like millions of people, lives with mental illness," Rosie's rep Cindi Berger told CNN. "It has been a difficult road for Chelsea and her family and they just want her back safe." She has not officially been classified as a "missing" person, but they are investigating until further notice. They have no information about the medication O'Donnell referred to in her blog post.

Rosie and Kelli Carpenter adopted Chelsea together when they were married. Carpenter shared a photo of Chelsea in a pink dress to her Facebook with the same statement as Rosie's post. "Please share on your social media in order to help find her," she added.
