Countdown to Christina...

Christina Aguilera REVEALED!

Blissfully married, with a baby on the way, Christina Aguilera is downright giggly about the future. Question is, is she still dirrty? The countown has begun — mark your calendars: The issue hits stands on December 11.

“We were planning on starting to try after the tour. And so, I had gone off the Pill to prepare my body, because I didn’t know how much time it would take. You’ve heard it takes some time — except with Power Egg and Super Sperm here ... I’m like, Oh, my God, can you believe it just happened?” said Aguilera.

Aguilera figures she got pregnant when Bratman was visiting her in Georgetown, during the U.S. leg of her Back to Basics tour.... Only problem was, she still had a month left on an eight-month world tour where she changes costumes at least 10 times during the show, hangs from a circus pinwheel, rides a carousel horse, plays a dominatrix, and wears major heels throughout:

“I was paranoid. There are so many things that could go wrong — somebody could slip, somebody could fall, I could fall. There was no way in hell I was going to jeopardize my baby for my show.” So she wore a well-concealed heart monitor. She didn’t want to broadcast the news. “I didn’t want to make the audience uncomfortable, like, ‘Pregnant lady onstage! Is she going to be okay?’ But I had to announce it to my band and my dancers, because I wanted to make sure they had my back.”
