Alex Rodriguez has been dogged by some rumors of alleged — or attempted — cheating during his engagement to Jennifer Lopez, and the latest comes from a former Playboy Playmate who says A-Rod was sending her inappropriate texts not long before he popped the question.

British model Zoe Gregory told The Sun on Monday that Rodriguez sent her a string of sexually explicit text messages, including one of his genitals. She says the texts kept coming over the span over several weeks from late-December to Jan. 22. A-Rod proposed to J-Lo in March.

“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,” Gregory claimed. “If he is doing this right up until the point he is proposing to her it is just not fair.”
