Christina Aguilera has revealed her burgeoning baby bump to the world on Instagram.

The singer confirmed earlier this year that she is expecting a girl with fiancé Matt Rutler.

She has now showcased her growing tummy on Instagram with a photo of herself and her partner.

The image's caption reads: "Baby loves NYC."

This will be Aguilera’s second child as she is already a mother to 6-year-old son Max, who was conceived with ex-husband Jordan Bratman.

The couple announced their engagement via Twitter back in February.

Aguilera meanwhile released her seventh studio album 'Lotus' in late 2012.
