Christina Aguilera is pregnant once again.

The 33 year-old is expecting a baby daughter with new fiancé Matt Rutler.

This will be the pair's first child together.

The pregnancy news comes just weeks after Aguilera announced that Rutler, who she has been dating for the past three years, proposed to her.

"He asked and I said..," she wrote, along with a photo of her hand wearing a huge diamond ring while holding his hand, with a pleasant beach scenery in the background.

Aguilera is already a mother to Max Liron, 6, her son whom she shares with ex-husband Jordan Bratman.

The pair walked down the aisle in November 2005, but after being married for five years they decided to separate, and their divorce was finalized in February 2011.

Aguilera met her new beau, Rutler, while filming 'The Burlesque' in 2010, he was working as a production assistant at the time.

Back in April 2011 the 'Genie In A Bottle' singer gushed to Parade magazine about her son always wanting his mother to himself.

"He doesn't really like to see mommy in work mode quite yet," she said. "He's so used to when he sees mommy, I'm in mommy mode, and mommy mode is all about Max. So as he grows up, he'll understand that side of mommy as a good example of being positive and driven and focused. But for now, he definitely wants mommy all to himself!"

However, despite the pregnancy news the 'Dirty' singer will not slow down her already very busy schedule. Today Aguilera posted a photo on her Twitter page of herself performing onstage in Malaysia.

"Ain't no other fans... Thank you Malaysia for all the love & support! XoXtina," she posted along with the pic.

Congratulations to the happy couple.
