Rosie O'Donnell, Michelle Rounds engaged -- Us Weekly

Rosie O'Donnell, who made her public debut with girlfriend Michelle Rounds in September, is now engaged to the New York headhunter. According to Us Weekly, O'Donnell announced the news to her studio audience at a Friday taping of her new "Rosie Show."

O'Donnell has four children with ex-wife Kelli Carpenter. The couple split in 2010 after three years of marriage. Before Rounds, O'Donnell briefly dated Tracy Kachtick-Anders -- a mother of six -- last year.

So far, O'Donnell hasn't mentioned anything about an engagement on her official Twitter account.

In an October interview with ABC's "Nightline," O'Donnell described the moment she first saw Rounds in a New York Starbucks:

"I thought she was a 28-year-old heterosexual girl, because that's what she looked like to me. And she's a 40-year-old gay woman. My gaydar was way off!"
