Christina Aguilera Pregnant With Baby No. 2

First comes love, then comes a proposal … then comes a baby?!
 
Christina Aguilera and fiancé Matthew Rutler are expecting their first child together. This will be the second kid for "The Voice" coach, who has a 6-year-old son, Max, with her ex-husband, Jordan Bratman.
 
Rutler popped the question to Aguilera, 33, on Valentine's Day.

The couple met on the set of her 2010 film "Burlesque" and have been dating for nearly three years.
 
This will be the second marriage for the singer, who was hitched to Bratman from November 2005 until October 2010.
 
So far, Christina has stayed mum about the happy news on Twitter.
 
We just have one question … boy or girl?!
