from www.nypost.com – Alex von Furstenberg’s frisky fiancée struck a sultry pose in a revealing black camisole and sent it to retired NBA star Reggie Miller during a three-month sexting marathon, photos show.

Ali Kay, 25, also posed in a blue push-up bikini for the current TV announcer, the shots reveal.

The racy pictures surfaced yesterday after The Post reported that Kay was a willing participant in a text-message relationship with Miller — batting down claims by von Furstenberg, 38, that the former Indiana Pacer was stalking his girl.

Von Furstenberg’s lawyer, Ronald Richards, said yesterday that Kay did not send the pictures to Miller. He declined to say who did.

Von Furstenberg — the son of legendary designer Diane and stepson of media mogul Barry Diller — was so steamed that Miller was phone-flirting with his bride-to-be that he hired a plane to fly over a Malibu beach last weekend, trailing a banner that read: “Reggie Miller Stop Pursuing Married Women!”

The stunt backfired when Miller’s lawyer, Marty Singer — noting that Kay isn’t married — told The Post that the text-relationship was a two-way street, with Kay even sending Miller the provocative pics.

Miller and Kay texted each other hundreds of time between March and May.

At one point in June, fuming fiancée von Furstenberg filled out paperwork for a restraining order against Miller, but never filed it in court.

Miller had also considered a restraining order against von Furstenberg, his lawyer said.

Meanwhile, court records show this isn’t the first time von Furstenberg has erupted in a jealous rage over his much-younger girlfriend, whom he began dating in 2003, while he was still married to Duty Free heiress Alexandra Miller.

That year, the fashion heir pleaded guilty to misdemeanor assault after he beat up a man who flirted with Kay. He later got the plea vacated in exchange for going to anger-management classes and doing a week of community service.

Von Furstenberg’s victim, Rowen Seibel, said he was sitting in his car at around 1 in the morning when Alex — also in a car — put his vehicle in reverse and repeatedly slammed it into Seibel’s, according to court papers.

Von Furstenberg then got out of his car, smashed Seibel in the face and head with his fist, threw him to the ground and kicked him, court papers allege.

When a cop showed up, von Furstenberg said, “I hurt my knuckle, probably when I hit him in the head.”

Asked about the incident, von Furstenberg’s lawyer noted, “That was almost a decade ago, and it was expunged.”

Von Furstenberg and Miller have said through their lawyers that they’ve resolved their issues.
