Gov. Andrew Cuomo is spending more time in Albany because his daughters are mostly all grown, he said Thursday during a radio interview — in which he didn’t mention longtime girlfriend Sandra Lee at all, amid rumors, first reported by The Post, that the two have split.

“What has changed is my girls are basically out of the house. I was living in Westchester. They were going to school. They’re now 22, 23, the youngest is in her last year of college. The other two are making their way and they’re living in Manhattan,” Cuomo said on WAMC’s “The Roundtable.”

Both Cuomo and celebrity chef Lee have denied a Post account in May that they had broken up after a 14-year relationship, and were living apart.

He has lived with Lee at her home in Chappaqua, which is now up for sale. A Cuomo insider and Lee Thursday insisted the couple is still together and the governor spent time at the Westchester residence in recent days.

Lee said all is fine with beau Cuomo. “Yes, and we are selling our house Honey — but thanks for asking. Wishing u the best,” she said.

Cuomo has three daughters with his ex-wife Kerry Kennedy — Maria, Michaela and Cara.

“My life is basically simple. As you know, I work and then I spend time with the family,” he told host Alan Chartock.

He spent a lot of time in the governor’s mansion when his father, the late Mario Cuomo, was governor from 1983 to 1994.

Mario Cuomo made the Albany mansion his permanent residence while in office.

“It is a little musty, because, well, it had a feel of a museum because no one really lived in it. It was homey when my mother was here and my father was here. My mother redid the whole mansion at the time,” the governor said.

“No one has lived in it since and they’ve just done periodic events. Also, I have a lot of fond memories here.”

During his first eight years as governor, Cuomo split his time between Albany and Westchester.

He claimed to spend more time in the state capital than predecessors David Paterson, Eliot Spitzer and George Pataki.

“I would go up and down often on the same day. But the people of the state come first except for my family … you’re not doing the right thing by your family, I believe that. That’s the inner concentric circle. If you’re not doing the right thing by your family … how can you do the right thing by anyone else,” said Cuomo.

“I did my best to do both, I have been more present in Albany, I have been more present around the state than past governors. I’m all over the place. I believe it’s important that you show up and I show up. But being a present, engaged father was my and is my first job. I believe that.”

Lee said all is fine with beau Cuomo. “Yes and we are selling our house Honey — but thanks for asking. Wishing u the best,” she said.
