Christina Aguilera certainly knows how to keep us in suspense!

The singer gave birth to her second child, Summer Rain, back in August, but she has waited until now to share a picture of her little one with the world!

It looks like the five-month-old is already taking after her mum, as Christina posted this sweet picture to Instagram yesterday of Summer wearing a nappy emblazoned with the words "Lil' Diva." 

Looks like we'll have to wait another five months to actually see Summer's face… but we have to say that nappy is pretty cute!

This is Christina's first child with her fiancé Matt Rutler, though she also has a seven-year-old son with ex-husband Jordan Bratman.

Since giving birth back in the summer, Christina has been preparing to kickstart her career with a new album, set to be released sometime this year. She will also be returning as a judge on the eight season of The Voice USA with Pharrell Williams, Adam Levine and Blake Shelton.

A busy year ahead!
