J. Lo, Marc, Max and Emme: MSG Valentine's Surprise!

While it wasn't all that long ago that rumors pointed to a Valentine's Day breakup, Jennifer Lopez and Marc Anthony looked ever-the-happy family in New York City on Saturday night (February 14).

With Max and Emme on-hand, the foursome surprised the audience by taking the stage and waving to the crowd following a dazzling and energetic performance by the 40-year-old Anthony at Madison Square Garden.

Earlier in the night, J Lo and Marc were able to squeeze in pre-concert time sans children at the upscale NYC restaurant The Post House, during which time Jennifer toted a cute little heart-shaped purse on the lover's holiday.

Building back up their appetite through the course of the evening, the two headed to Cipriani after the show, sending the kids home with helping hands.
