Christina Aguilera Bares Her Baby Belly

ET has the latest... Pop star CHRISTINA AGUILERA reveals her growing baby belly and more in the January issue of Marie Claire , on stands December 11. On the cover, the expecting mom poses wearing nothing but a cropped jacket, proudly showing off the belly she kept hidden for months. But the article inside is just as attention-grabbing, with the singer opening up about her "surprise" pregnancy. "We were planning on starting to try after the tour," she says. "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?'" Christina says getting pregnant so quickly left her in a bit of a bind regarding the tour. She had a month left to go and each show consisted of 10 costume changes -- including major heels, hanging from a pinwheel and riding a carousel horse. [link]
