J.Lo and A-Rod take their love out to lunch

Jennifer Lopez and Alex Rodriguez brought their budding romance to Central Park South on Thursday — strolling arm in arm after a nearly three-hour feast of seafood and homemade pasta.

“They were both so happy,” one spy told The Post of the amorous A-listers. “Really, really happy.”

The pair have been dating for two months, and their lunch date at the Midtown Italian favorite Marea (Italian for “tide”) shows the relationship progressing swimmingly.

They arrived separately at 12 p.m., dressed for upscale lunching — J.Lo in a black-and-white knit dress, and A-Rod tie-less but in a crisp blue suit with pocket square.

They joined a table with three other diners. And they didn’t leave until 2:30, departing the restaurant with linked arms.

“J-Rod” then left together in a waiting, chauffeured, uptown-bound car.
