Alex Rodriguez places his hand on Jennifer Lopez's as he treats her to jewelry shopping on Valentine's Day

He may have treated her jewelry shopping but Jennifer Lopez seems to have all the booty Alex Rodriguez needs.

The 42-year-old former baseball player treated his 48-year-old girlfriend of one year to some jewelry shopping in Miami for Valentine's Day on Wednesday.

At one point Alex even cheekily placed his hand on J-Lo's famous derriere as she hunched over to look at the display case.

No doubt both stars know a lot about the finer things in life as they stopped by both Mayor's Jewelry Store and Tourneau Watches in the South Eastern party city.

It was plain to see why A-Rod couldn't keep his hands off the stunner as she showed off her fab figure in a clinging nude midi dress.

The sleeveless dress showed off her curvaceous figure as she paired it with matching patent leather heels.See more photos below;
