Rosie O'Donnell has split from girlfriend Tracy Kachtick-Anders, the New York Post's Page Six reported.

The 48-year-old comedienne, talk show host and actress confirmed last year that she was dating Kachtick-Anders, an artist and mother of six.

“They have definitely split up,” a rep for O'Donnell told the paper, “but it is very complicated because their kids are very close.”

O'Donnell, who came out gay in 2002, married Kelli Carpenter, a former Nickelodeon marketing executive, in 2004 in San Francisco, California. The two women share four children. They split in October, 2009.

O'Donnell and Kachtick-Anders remain next door neighbors in Nyack, New York and reportedly their families continue to socialize together.

In September, O'Donnell, who is planning a return to daytime television on Oprah Winfrey's OWN, enthusiastically talked about her new love: “Tracy has six kids, she lives next door … It's a lot! We're the Gay-dy Bunch! It's a challenge, but when you fall in love with someone, they come with a whole bunch of things, including children.”

She previously described Kachtick-Anders as “almost too good to be true!” and a “lovely, lovely, lovely person.”
