Xtina to Newborn Son: Lullabye Bye Bye

Christina Aguilera's not like regular moms, she's a cool mom -- one who'd opt for club hopping instead of listening to a baby monitor all night.

With her 4-month-old son Max sleeping at home, Xtina and her hubby got their party on again at Villa -- her second time out this week, sixth this month. She'll cap it off by hosting a party at LAX in Vegas this weekend. A mother's work is never done.
