SWIZZ BEATS FINALLY PROFESSES HIS LOVE 4 ALICIA & GOES THRU THE BABY MOMMA DRAMA!

Hip-hop maestro Swizz Beatz is finally admitting that he and Alicia Keys are an item — but he wishes his estranged wife, Mashonda, would leave the Grammy winner out of their divorce.

For months now, Swizz has been trying to keep his thing with Alicia on the down-low. But he doesn't leave much doubt about who owns his heart on Drake's new "Best I Ever Had" remix.

Wake up in the morning and my baby cooked me breakfast, A's naked wearing nothing on but a necklace …

Yeah, she say she wanna treat me like a king; I get big gifts so the money ain't a damn thing

She gave me a party at the Guggenheim … What's next? The ring? The baby? She really loves me!

Swizz tells us that, yes, he's in love with Keys and, yes, she did give him a birthday party at that museum.

"But we're nowhere near ready for a baby or a ring," laughs Swizz, aka Kasseem Dean. "This whole song is not about Alicia. The part about her cooking breakfast for me naked — she never done that for me." Damn.

Swizz didn't want to talk about Keys till now because, he says, "What we have is so precious." He also felt it would aggravate Mashonda, who's also a singer.

He may have been right. "When he told Mashonda he was dating Alicia, I think she got jealous," says a friend of the couple.

Having filed for divorce in February, Mashonda is seeking interim support for their 2-year-old son, Kasseem Jr., arguing that Swizz has slashed his payments.

"He's been tightening the screws on her," says a friend of Moshanda. "It's becoming intolerable. Meanwhile, she's seen the charges for jewelry he's bought Alicia in France."

During the winter, the heat in Mashonda's Westchester mansion went out. "Swizz wouldn't repair her heat," says her friend. But a pal of Swizz argues, "The house is 30,000 square feet. The heat didn't work in one wing, not where Mashonda and Dean slept. Swizz had been paying all of their bills. On top of that, he was giving her $5,000 a week. His advisers felt that was too much, so now he pays her $3,500 a month, on top of the bills.

"Swizz has put settlement offers on the table, but Mashonda won't say what she needs. She just came back from Paris and London. She drives a Bentley Flying Spur and a Cadillac Escalade. I don't think life's too bad for her."

Mashonda's friend argues that she's resisted his offers "because he's been less than forthcoming about his true financial picture."

Swizz's lawyer, Dan Rottenstreich, insists, "He has taken care of her and his son above and beyond what's required."

Says Mashonda's attorney Bernard Clair: "An application is pending before the court, where the facts will be developed."
