Justin Bieber is definitely not sorry for turning 22. The singer-songwriter is celebrating his birthday today and we have one guess as to how he's spending it: with his siblings (and perhaps his rumored girlfriend, model Hailey Baldwin).

The star—who is about to kick off his Purpose World Tour this month—has both a younger brother and sister, Jaxon, 6, and Jazmyn, 7, and while Bieber has since moved on from his bad boy days, he's currently focused on being a great older brother. In fact, Bieber took his little brother Jaxon as his plus-one to the 2016 Grammy Awards and even shared a few sweet red carpet moments with his mini-me.

What's more, Jaxon is well on his way to being as famous as his older brother, already racking up more than 825k followers on Instagram. His first post? A video of himself singing "I'm Sexy and I Know It."

In honor of Bieber's 22nd birthday, we're taking a look at 11 of his sweetest big brother moments from Instagram, all of which will be sure to garner an "aww" or two.
