Jennifer Lopez uses $19K Hermès Kelly as gym bag

Her love might not cost a thing, but her gym bag will set you back a pretty penny.

On Wednesday, Jennifer Lopez stopped by Miami’s TruFusion gym for a workout with boyfriend Alex Rodriguez, where she matched her neon-green Nikes with a bright yellow Hermès Kelly bag. The price of the pop icon’s purse? A cool $18,500.

J.Lo’s no stranger to stylish splurges, of course: In March, she and A-Rod picked up a $15 million Park Avenue penthouse together, and the “Dinero” singer prefers to unwind at a $35,000-per-night Mexican resort.

No word on whether the star stashed the rare handbag in a locker during her sweat session.

Inside, Lopez and Rodriguez worked out with 200 fit fans and a DJ spun tunes in the lobby.

Said a pal of the class where A-Rod worked out shirtless, “It was a giant party.”

Perhaps the couple will next turn up at a new TruFusion pop-up in the Hamptons?
