Hot Gossips Of Celebrity: Christina Aguilera

Christina Aguilera says she's become sexier since welcoming son Max in January 2008.

"I'm more confident and comfortable in my own skin. I think I'm even a more sexual Christina," the singer, who wed husband Jordan Bratman four years ago, told the Q100 Bert Show in Atlanta Tuesday morning.

"That's part of the change of having a child for me -- seeing your body do these things you never thought possible," adds Aguilera, who will release her album, Bionic, on June 8 and kick off a world tour to promote it. “When you have a baby, you go through a period where your body is not your own. It becomes for your child and that's it. Once you bounce back from that and kind of get your body back... I feel better than ever. It's a great feeling."

Aguilera, 29, says she's a "very sexual person" and she didn't want to lose that after becoming a mother. Indeed, she and Bratman still have "Naked Sundays."

"I think it's important that he sees mommy not be ashamed for her sexuality," she says. "I mean, he's two. We're art collectors, there are a lot of female nudes around the house. Max will be growing up in a house where it's just the norm... It's only weird when you shame it...."

Max may not be an only child forever.

When asked if she wants more children, Aguilera says, "I would love that one day, but not right now. Eventually, I would like to give Max a brother or a sister, but right now, Bionic is the baby."

Aguilera also addressed online criticism that she's copying Lady Gaga with her new album.

"It just comes with the territory. That, in particular, is not even worth wasting the breath to comment on," she sniped. "I've been around for over a decade and I think my work speaks for myself."

If she were younger, "I would have engaged, been a little upset," she says. But now? "There's a bigger picture out there. I've got my son, my family, my work."
