Rosie O'Donnell has a new girlfriend, according to a new report, and her new gal pal is married to a man.

Radar Online reports that Rosie, 54, is dating former Broadway actress Dana Schiff, who is a longtime friend of "The View" host. Dana is married to Scott Schiff, an investment banker, and the couple have two children together.

Scott, however, has been growing suspicious and is reportedly losing weight over the alleged relationship.

The report alleges that after Dana, 48, puts her children down for bed, she leaves to spend time with Rosie.

"Dana's late-night escapades became so frequent that even the building's doormen began to suspect that she was having an affair," a source told Radar, who added that Dana has begun to change her physical appearance in recent months. "She stopped wearing dresses, and cut her hair short. I think she was trying to look different because of her new relationship with Rosie."

The report says Rosie has been trying to tell people that Dana is her new employee.

When contacted for comment, Rosie told the website that she and Dana were friends, while Dana says she has "absolutely no comment."

Dana, who starred in "Cats" and "Les Miserables," was actually with Rosie during her well-documented run-in with Ivanka Trump at New York's Nobu restaurant in October.

They were also together at Nobu in early January with TV director Norman Buckley.

"A really lovely evening with Dana Schiff, Rosie O'Donnell @rosie, and Rosie's son Blake," Norman captioned a photo of the group. "We went to see Stacyann Chin's one woman show #Motherstruck, which Rosie produced."

Rosie is the godmother of Dana's daughter, Plum. Dana and Scott were married in 2003.
