Madonna is hoping to make Alex Rodriguez jealous with her new man Jesus Luz, it's claimed.

The recently-divorced queen of pop is said to be flaunting her romance with the Brazilian model in a bid to make her rumoured lover A-Rod green with envy.

A source tells the New York Daily News, "Madonna likes to be in control, and she hasn't been able to completely control Alex yet.

"Jesus has been much more attentive than Alex recently. If A-Rod will commit to Madonna, then he'll win her affections.

"But it's not like he's giving her a diamond ring. Neither he nor Madonna is 100 per cent committed to each other yet."

The source adds, "Alex is well aware that Madonna is out and about with Jesus, and he isn't happy about it.

"It's embarrassing for him because he and Madonna have been so publicly linked, and now it looks like he's been dumped for a younger stud.

"Jesus comes and goes, but he never stays at her house. He's certainly not moving in. It's not like Madonna is going to marry Jesus. He's keeping her warm at night."

Things betwen the New York Yankee and Madge seemed to cool off after Christmas - paving the way for Jesus who allegedly wooed the singer on location in Rio de Janeiro.
