Rosie O'Donnell thinks her fiance is "perfect."

The comedian announced her engagement to headhunter Michelle Rounds last month.

Rosie feels that she has found an ideal mate in Michelle.

"I'm not a Barbie. She has Mattel stamped on her a*s," Rosie told Us Weekly at the National Board of Review Awards Gala in New York City this week. "She's literally perfection."

Rosie is in awe of their upcoming union. Michelle is so perfect that the engagement feels like somewhat of a dream to Rosie.

"She's like Ann-Margaret," Rosie said. "I constantly go, 'Are you sure you want to do this?' "

Rosie deeply appreciates Michelle's character.

"She's so unbelievably connected and refined," Rosie gushed. "I so love her embracing her femininity in a real feminist manner. To be able to be a lesbian, feminine, feminist is pretty sexy."

Rosie and Michelle are busy with wedding planning. Rosie is not finding the formalities of the process particularly simple.

"It's kind of weird, like we met with some swanky-a*s people," Rosie said.

Rosie and Michelle met at a Starbucks coffee shop last summer.

The pair will wed this spring.
