Rosie O'Donnell & Michelle Rounds Trying For A Baby!

Another baby for talk host Rosie O'Donnell? She and fiancee Michelle Rounds haven't been engaged for long, but the couple are already planning to start adding to their family.

"She's trying to get pregnant," O'Donnell told Dr. Mehmet Oz of Rounds on Friday's (January 27) episode of her OWN show.

"Michelle is seeing a fertility doctor," a source close to Rosie tells Us Weekly. "She is really excited and they cannot wait to add to their family. Rosie goes to all of her doctors' appointments with her and is really supportive. She isn't pregnant yet but they hope as soon as possible she will be."

In addition to their baby plans, the happy couple is also busy with wedding plans. Insiders say that the ceremony - though more traditional than O'Donnell's nuptials to Kelli Carpenter - will be very low-key, and involve Rosie's four children - Parker, 16, Chelsea, 13, Blake, 11, and Vivienne, 9.

"She is thinking of having her brother walk her down the aisle," says the source. "She wants a proper, traditional wedding this time around. Michelle will say vows to the kids as well as Rosie."
