Ok, seriously. How cute is this?

Justin Bieber is an adoring big brother, and he admits to spoiling little Jazmyn and Jaxon. Pictures like this make it easy to see why. They're absolutely precious!

Pictured with his siblings is his own proud papa. Captioned, "What is it buddy," The Biebs is clearly bonding with little Jaxon. His goofy expression and the little ones' big smiles could melt even the iciest heart. Considering he posted this near Christmas, maybe he was asking what's in his stocking!
