Stina Kayy is officially 29 years old … and in honor of her birthday today, let’s take a look back at some of her bustiest snaps.

The Canadian YouTuber, singer and model also has another clear talent to add to her impressive résumé … posting her jaw-dropping assets on Insta!

What better way to ring in her new year than by taking a scroll down memory lane.

Look at this nearly naked pic … Stina proved that less is definitely more with her selfie game.

Seriously, this black and white outfit proves that mesh bikinis are so in … especially when her chest is so out.

Speaking of bikinis … summer may be in its final days, but this hot pink two-piece gives us all some motivation to hit the beach before fall officially starts!
