Rosie O’Donnell has moved her new girlfriend into her home after her wrenching split from wife Kelli Carpenter, The ENQUIRER has learned exclusively.

Rosie’s new love is Texas artist Tracy Kachtick-Anders – a 45-year-old mother of six who’s living in Rosie’s waterfront mansion on Florida’s ritzy Star Island.

The pair met in October during an online chat on Rosie’s Web site and began trading artwork, sources say.

"They hit it off instantly, and Rosie invited Tracy to spend time with her in Florida," divulged a source close to the 47-year-old comedian.

"But Tracy could stay only briefly because she was tied up taking care of her family in Galveston.

"Rosie suggested that she bring the kids to Florida for Christmas and New Year’s so their families could be together for the holidays. Now Tracy has moved in."

Tracy’s children range in age from 5 to 17. Five of her children are adopted. She gave birth to her youngest, a boy with Down syndrome.

She’s also a writer, gay activist and children’s advocate who created a nonprofit volunteer organization called the Open Arms Campaign
