Britney Spears
is still the spitting image of her younger self! 

The pop star turns 32 years old today -- and, to celebrate, Brit's sister Jamie Lynn Spears shared one adorable vintage snap.

"Happy Birthday Brit!!! I know your an idol and icon to many, but most importantly your an amazing mother, friend, Aunt, and sister!!! Love you!! Hope you have an amazing day- you deserve it!! #happybirthdaybritney," she posted along with the cute Instagram pic. 

Spears is seen holding a very little Jamie, alongside her brother Bryan Spears. She sure hasn't changed much -- the "Perfume" singer still has the same adorable smile!
