Rosie O'Donnell: 'Fiancée Michelle Rounds is literally perfection'

Rosie O'Donnell has described fiancée Michelle Rounds as "perfection".

The talkshow host, who announced her engagement to Rounds in December, confessed that she feels lucky to have found a woman who so closely resembles a Barbie doll.

"She's like Ann-Margret. I constantly go, 'Are you sure you want to do this?' " O'Donnell told reporters at the National Board of Review Awards Gala in New York City on Tuesday.

"I'm not a Barbie. She has Mattel stamped on her ass. She's literally perfection."

Asked what other qualities she admires about Rounds, O'Donnell answered: "She's so unbelievably connected and refined. I so love her embracing her femininity in a real feminist manner. To be able to be a lesbian, feminine feminist is pretty sexy."

Last month, O'Donnell revealed that she and Rounds had been secretly engaged for months as they had been hesitant to publicly announce their engagement.

The 49-year-old confessed that she was nervous to propose and did so with her head down.
