Rosie O'Donnell's estranged wife Michelle Rounds was rushed to a New York area hospital late Tuesday night after attempting suicide inside a hotel room, Breaking Celebrity News has exclusively learned.

A source told Breaking Celebrity News that Rounds, who is involved in a nasty divorce and custody battle with the former TV talk show host, had checked into the DoubleTree hotel in Nanuet earlier in the day.

She was reportedly alone, without Dakota, 2, the adopted daughter at the center of her nasty custody fight with O'Donnell.

The hotel is near Rounds' residence in Nyack, where O'Donnell also owns a home. As Breaking Celebrity News reported, O'Donnell recently moved her new girlfriend, Tatum O'Neal, into her home.

According to the source, an unidentified person who was concerned about Rounds contacted police.

Officers from the Clarkstown Police Department from nearby New City immediately responded to the call, and according to a second insider, were forced to break down the door to Rounds' room.

"She had apparently taken some pills and drank wine," the insider reveals. "It looked to be a suicide attempt "

Breaking Celebrity News can confirm that Rounds was taken to Nyack Hospital, where she remains under doctors' care today. Her medical status is currently unknown.

O'Donnell, 53, and Rounds, 43, split in February after two years of marriage. The divorce has been acrimonious, with nasty back-and-forth over the custody of Dakota.

The chaos may have led to the "cry for help," the insider claims.

"Michelle was very depressed lately over the divorce and custody battle with Rosie," the insider reveals. "In fact, in the past few days her and Rosie spoke and they had a bitter argument."
