J.Lo & Marc Party the Night Away in Miami Beach | Jennifer Lopez, Marc Anthony
Forget a quiet night in: Mom-to-be Jennifer Lopez and Marc Anthony spent their night off from their joint concert tour with 120 close friends, throwing an all-night private party at Glass, a sexy spot in South Beach's the Forge restaurant.

Lopez, in a maroon mini dress and silver sandals, cradled her stomach as she danced and laughed with party guests while DJ Irie spun salsa tunes. "Jennifer was dancing up a storm," says a source. "She and her friends perched themselves under an arty picture of David Bowie and danced all night." The singer was also affectionate with her husband. Adds the source: "She and Marc were so sweet together, constantly kissing, hugging and holding hands."

There was also plenty of food. At one point, one of the tour assistants drove to a nearby Dunkin' Donuts and brought back some late night snacks. Another sweet highlight: a big ice cream cake, which partygoers (Lopez included) enjoyed as the group celebrated several birthdays and continued partying until early the next morning. –Linda Marx
