Christina Aguilera Defends Her Late Nights | Christina Aguilera
Make no mistake, Christina Aguilera loves her baby. But she likes the nightlife, too.

"Once in a while, if I want to go out and have a mommy-daddy night with my husband, I am more than allowed to do that," the singer – who gave birth to son Max Liron in January – told Access Hollywood.

This past weekend, for example, she hit Las Vegas's Pure nightclub at Caesars Palace to help celebrate the launch of an Xtina-inspired jewelry line, the Stephen Webster Silver Collection.

"I spend all day with my son," Aguilera, 27, told the TV show – adding that any criticism of her late-night outings with husband Jordan Bratman is downright "mean spirited."

"Everybody has an opinion and everybody sometimes wants to cause drama," she said. "But it's something that comes with what you do and I learned that very early on."
