ROSIE O’DONNELL is officially engaged to partner Michelle Rounds.

The feisty funny gal, 49, told her Rosie Show studio audience Friday  she and Rounds will tie the knot  over Christmas.

Back in September, Rosie and Rounds, a New York City headhunter, made their public debut at the Rosie Kids Gala in New York City. 

But as The ENQUIRER reported in our Oct 31, 2011 print edition not everyone is happy with the upcoming nups.

“It totally hit us out of left field,” Michelle’s father Roger Rounds revealed in an exclusive ENQUIRER interview. “We only found out about Michelle liking girls when all this came out about them a few weeks ago. It’s been hard to take!”

Not only that but Rosie had claimed that she had met both of Michelle’s parents prior to her nationally outing Michelle.

But Michelle’s father slammed Rosie, saying that’s a big FAT lie!

“I’ve never met the wom­an – and I have no real desire to at this point!” Roger fumed.

 “This has been a painful experience for me and my wife,” he continued.

“It’s pret­ty shocking stuff for us to digest.”
