Christina Aguilera is expecting a girl.

The 'Fighter' singer and her fiance, Matthew Rutler, are having a daughter according to JustJared.com, which will be their first child together.

The girl will be a sibling to Max, Christina's six-year-old son with ex-husband Jordan Bratman.

The singer is currently in Malaysia, where she performed for fans tonight (28.03.14), writing on twitter following the show: "Ain't no other fans... Thank you Malaysia for all the love & support! XoXtina (sic)"

Christina, 33, announced she was expecting in February, a week after Matthew had proposed and is said to be over the moon with the pregnancy, with one source saying: "It wasn't expected, but it also wasn't unwelcome. They are all very excited though! Christina loves being a mom."

Production assistant Matthew met the blonde beauty on the set of movie 'Burlesque' in 2010 while she was going through her divorce, and had been planning to propose long before Christina got pregnant, even starting to design her engagement ring more than a year ago.

He popped the question in the backyard of their new home in Los Angeles, which is still under construction, on Valentine's Day.

Christina was said to be completely "shocked" by Matthew's romantic sunset proposal, for which he wore a suit and filled a gazebo with candles and red roses, before taking her to celebrate with friends and family.
