Rosie O’Donnell’s partner of four years, former marketing exec Kelli Carpenter, 34, is several weeks pregnant, confirms a friend of the talk show host’s to PEOPLE. The pal tells the magazine (in the issue due to hit newsstands Friday) that O’Donnell and Carpenter visited a sperm bank not long ago. There has been no word on the identity of the donor. “To me,” O’Donnell, 40, has said, “biologically born or adopted is no different. You get the child you’re supposed to have.” Already a parent to three adopted children (two boys and a girl) — Parker, 6, Chelsea, 4, and Blake, 2 — O’Donnell has always dreamed of “having lots of kids,” she told PEOPLE in 2000. How many would be “lots”? “I would love five or six,” said the entertainer and Rosie magazine publisher, who has four siblings. “Nothing would be better for me.” Nor could the timing be better for soon-to-be full-time parents O’Donnell and Carpenter, what with best-selling author (“Find Me”) Rosie wrapping up her TV show duties this month. “They love each other very much,” says the pal about the couple. “They’re thrilled.”
