Jennifer Lopez and Marc Anthony took a break from diaper duty with twins Max and Emme Tuesday night, when they opted for a romantic, adult dinner at Andrew Hewitt's new Pacific-Rim-inspired Beverly Hills restaurant, Luau.

The couple - the subject of recent rumors about their state of their marriage - snuggled together in a booth, feeding one another Kobe meatballs and enjoying tamarind-glazed ribs, as well as each other's company, if their kisses were any indication.

Lopez, sipping an apple martini, and Anthony, drinking beer, "looked genuinely in love," observed one diner.

Also adding to the festive atmosphere: a fellow patron's toddler, who sprinted the Anthonys - who couldn't help but fawn over the child.

Still to come was dessert, coconut tiramisu and chocolate lava cake, which the happy couple shared.

As for reports the couple have been seen out and about without each other, says Marc's rep, Blanca Lasalle, "They are doing great. [These] are fabricated stories. They are together. He had a boys night out. She had a girls night out. There is nothing wrong with that."
