Ex-Playmate claims A-Rod was sexting her weeks before proposing to J.Lo

A former Playboy Playmate reportedly claims that Alex Rodriguez sexted her, practically begging for a threesome — just weeks before his storybook proposal to Jennifer Lopez.

Model Zoe Gregory, 44, says the ex-Yankee slugger sent her a photo of his equipment with a text asking for names of “fun girls for [him and me],” according to The Sun newspaper in London.

“He was being like a dirty dog. He seemed like a needy, horny bloke,” Gregory told the newspaper. “If he is doing this right up until the point he is proposing to her, it is just not fair.”

A-Rod, 43, allegedly showered the model with compliments while asking for “naughty videos” and a rendezvous with a third partner in San Francisco.

“She hot? Fun? How many times have you been with her?” A-Rod purportedly asks in texts provided to the paper.

He allegedly asked for “dates you can fly out (maybe next week to SF),” according to the texts.

Rodriguez also sent a selfie that showed “his penis and muscly thigh,” Gregory told The Sun, adding that he was enamored with her 36DD bust.

The messages, which began the day after Christmas, suddenly stopped in late January, Gregory claims.

Much to her surprise, A-Rod proposed to J.Lo, 49, earlier this month with a $1.8 million ring during a vacation in the Bahamas.

An image of the picturesque scene, on a beach at sunset, was posted on Instagram last week.

“Locking it down. 💙 #futuremrsrodriguez,” he wrote.

The 16-carat, emerald-cut diamond was purchased after months of “painstakingly” searching for the right ring, sources told Page Six.

Lopez flashed it Sunday as the couple headed to Polo Bar in Manhattan.

Gregory says “Jenny from the Block” is too good for the damn Yankee.

“J.Lo needs to wake up. I feel bad for her and I don’t think it’s right,” she told The Sun.

“J.Lo is amazing and she doesn’t deserve this. While getting ready to marry her, he was asking me for sex videos, demanding we hook up and asking me to make arrangements with other girls.”
