InTouch reports that A-Rod spent a recent visit to Miami surrounded by women.

A friend of A-Rod says, "When she’s not around and he is left to his own devices, he wants the company of other beautiful women. He can’t help it. It’s in his nature."

He was also seen dropping model Melissa Britos off at her hotel early one morning.

One of the model's friends said, "He became obsessed with her. He sent her at least a dozen text messages, asking her to spend time with him."

Will Madonna dump A-Rod's ass? Will A-Rod run off into the sunset with Britos?
