Nearly a week after the singer announced her engagement to Matt Rutler on Twitter, Us Weekly is reporting exclusively that Christina is pregnant again! According to the magazine, a close source to X-tina has confirmed that she is expecting with now fiance Rutler.

Adding fuel to the rumor-mill, Matt Rutler's mother confessed in a recent interview with InTouch, "I don't know what their plans are. But when you have a baby, you're not planning on moving anywhere anytime soon!"

Aguilera, 33, welcomed son Max with now-ex-husband Jordan Bratman in January 2008. The singer has really come into her own with a stunning weight-loss transformation and her role on the hit singing competition, 'The Voice.' While Christina may not be returning to 'The Voice' this season, we'll be keeping a close eye on her as she and her baby bump grow!
