Well would you look at these two cuties!

Shawn Mendes must have woke up feeling sentimental this Tuesday morning (October 15), because the "Lost in Japan" star just posted the cutest throwback video on Instagram of him and his younger sister, Aaliyah Mendes. The adorable clip takes it all the way back to the siblings' toddler days, as a pint-sized Shawn can be seen making his baby sister smile and giggle as she rides in her toy car before beaming a smile of his own at the camera.

If you didn't know, Aaliyah is a bit of a celebrity of her own. The social media star first gained popularity under the name Princess Aaliyah on the now-defunct video app Vine, on which she had 200,000 followers before it shuddered. Even so, she's pretty popular on Instagram, with more than 1.2 million followers to date.

Like any good big brother, Shawn never misses an opportunity to show his sister some love — especially on Instagram.

In fact, it was just a month ago that the "There's Nothing Holding Me Back" crooner celebrated Aaliyah's birthday with a shout-out on IG. "Happy 16th birthday to the most wonderful girl I know. I absolutely adore you ❤️" he captioned a gallery of nostalgic baby photos of his sister. And the month before, Shawn gave her the most heartwarming smooch on the cheek we've seen. (Ugh, could he be more perfect?!)

See the video of Shawn and Aaliyah — and more of their cuteness — below.
