One of each! Christina Aguilera is expecting a baby girl with fiance Matt Rutler, a source confirms to Us Weekly.

Us exclusively broke news on Feb. 20 that Aguilera, 33, and Rutler are expecting their first child. The announcement came just weeks after the "Fighter" singer announced the couple's engagement via Twitter.

"He asked and I said……" she captioned on Valentine's Day, with a snapshot of her gorgeous new diamond ring. The Voice mentor and Rutler first met on set of her 2010 film Burlesque.

Aguilera is already mom to son Max, 6, whom she had with ex-husband Jordan Bratman. The pair tied the knot in November 2005, but split five years later. They finalized their divorce in February 2011.

Back in November 2010, the singer gushed about their baby boy while visiting The Ellen DeGeneres Show. "He's the love of my life, and I adore him," she said of Max. "He's such a character, and he's so happy and at the end of the day, that's what's most important."
