AceShowbiz - Alex Rodriguez is hit with another cheating allegation. The 43-year-old former professional baseball player is accused of sexting glamor model Zoe Gregory, just weeks before he proposed to his now-fiancee Jennifer Lopez.

Speaking to The Sun, Zoe claims the sportscaster began to pursue her after he texted her a day after Christmas last year. It's unclear how they got to know each other or how he got her phone number, but the Playboy Playmate says he soon began pestering her to meet in person and begging her to bring friends for a threesome.

He allegedly bombarded her with sleazy texts and sent a picture of his manhood. Zoe additionally says that he tried to seduce her with compliments on her curvy figure and 36DD boobs, and asked her to send him sexy videos in return.

Showing his alleged text messages to her, Zoe disses the former MLB star, "He was being like a dirty dog. He seemed like a needy, horny bloke." In a message sent via WhatApp, he allegedly asked her, "Are you still thinking of your three names of fun girls for us?"

Alex reportedly also inquired Zoe about her friend for a threesome. "She hot? Fun? How many times have you been with her?" read the text message. In another message, he allegedly wrote, "You owe me two things; 1. Your old naughty videos 2. Dates you can fly out (Maybe next week to SF)."

While she doesn't say if a rendezvous between her and Alex ever happened, Zoe seems to be rooting for Jennifer. "J.Lo is amazing and she doesn't deserve this," she tells the webloid. "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."

Zoe says Alex stopped writing to her after January 22. The model, who now works as a fitness trainer, adds, "If he is doing this right up until the point he is proposing to her it is just not fair." She goes on saying, "J.Lo needs to wake up. I feel bad for her and I don't think it's right."

Alex proposed to Jennifer on March 9 during their their romantic Bahama getaway. Soon after breaking the news on Instagram, Alex was accused by Jose Canseco of cheating on Jennifer with Joe's ex-wife Jessica Canseco.

Setting things straight, Jessica later took to Twitter to deny any romantic relationship with Alex. "Those false accusations Jose is making are not true!" she wrote on March 12. "I have known Alex for many years and haven't even seen him for over 5. I certainly did not sleep with him. I am friendly with both him and Jennifer. As for Jose he can keep playing with his Alien friends."
