Page Six reported that Jennifer, 49, and Alex, 43, dined at Upper East Side hotspot Serafina in New York City.
Jennifer was apparently tardy for the party, as an eyewitness claimed she was thirty minutes late to their dinner outing!
The baseball legend didn't seem to mind her lateness. "He looked so much in love,” said the Page Six spy.
Jennifer's old pal Matt Dillon was dining elsewhere inside the restaurant.
The Video Music Award winner has been busy filming her upcoming movie Hustlers in The Big Apple.
She suffered a major wardrobe malfunction on set over the weekend when her skintight dress rode a little bit too high on her.
