Christina Aguilera is pregnant with her second child, reports US Weekly. She announced just last week on Twitter that she is engaged to her boyfriend Matt Rutler, a production assistant who works on movie sets. The pair have been together for nearly three years; they met while Aguilera was filming "Burlesque" in 2010.
Aguilera, 33, has a six-year-old son named Max with ex-husband Jordan Bratman. She is taking off season six of "The Voice"; Shakira will be filling in during her absence.
