Trouble in paradise?

Even though Jennifer Lopez and Alex Rodriguez’s relationship is only just beginning, it seems the duo is already facing problems as a result of Jennifer’s control issues.

The baseball player is allegedly “terrified” of his booty-shaking bae because of a long list of rules and demands she’s given him.

“It reads like some kind of style bible,” a source told Radar Online. “He’s totally under her thumb.”

On the heels of her breakup with Drake, the insider revealed that J.Lo is wary of A-Rod’s reputation as a womanizer.

“He’s very lucky she’s giving him the time of day, given his bad reputation,” the insider said. “Jen’s not making the mistakes she made with Drake and Alex is banned from being seen with any other woman under the age of 40.”

The mother-of-two is also making sure that her athlete beau is living up to her fashion and red carpet standards.

“She’s also given him an approved wardrobe list and a list of instructions on where to stand next to her on red carpets,” said the insider.

And even though Jen’s rules are intense, we can’t help but think that Alex doesn’t mind too much. As In Touch previously reported, the Yankees star has been “obsessed” with the “Jenny From the Block” songstress “for well over a decade” before their relationship blossomed.

“But he always had a girlfriend, and that bothered her. She didn’t know if she could trust him,” the source said. “It’s always been obvious that he was extremely into Jennifer.”

Though things have been rocky in terms of the 47-year-old's love life, moving from one high-profile relationship to the next, we hope that this A-list duo can work it out!
