Stunning singer Christina Aguilera is expecting her second child and guess what? She's having a baby girl.

Xtina, 33, is having a terrific year on the personal front. The singer is newly-engaged to longtime boyfriend Matthew Rutler. They were betrothed on Valentine's Day and the news that she was expecting leaked shortly thereafter. E! reports that she revealed the baby's gender at a fan event in Malaysia today (March 28).

The singer and 'The Voice' coach will now have a child of each sex, as she is already mom to son Max, 6. Max's dad is ex-husband Jordan Bratman, from whom Aguilera split in 2010 after five years of marriage.

Now, Max is getting a baby sister to love and protect, while Xtina will have someone to whom she can bequeath her enviable and fabulous wardrobe and sense of style! We bet she'll totally be a Mini-Me.

Aguilera, who is on hiatus for this season of 'The Voice,' has been dating Rutler since 2010. They met on set of her film 'Burlesque,' which also starred Cher. Rutler was a PA on the set of the film.

We bet Xtina is already thinking about names for her pink bundle-of-joy-to-be! We're waiting for her to debut the baby bump, too.

The PopCrush staff extends a warm congrats to Xtina, Rutler and little Max on their future daughter and little sister.
