Congratulations are still very much in order to Rosie O'Donnell and fiancee Michelle Rounds, but the talk show host told her studio audience today that the couple has been engaged for weeks.

She merely chose last Friday to go public with the good news.

"Michelle said to me a few months ago, when we got engaged, she said, 'How come you didn't say it on your show?' And I was like, 'Honey, I don't know how.' I didn't know how to say it," O'Donnell said yesterday.

Joking about a certain Two and a Half Men star, Rosie added about her reticence to talk openly about Rounds:

"You don't want to become one of those celebrities that talks about their relationship ad nauseum and makes it into a fairy-tale thing. And then they go and have an affair with somebody. I don't want to say any names."

Don't worry. We'll do it for you.
