Justin Bieber's little brother is an adorable mini-Biebs on the first day of school!

Is Justin Bieber's brother following in his pop star footsteps?

"Never Say Never!"

One thing's for sure - the cute 6-year-old is already adopting his famous half-brother's style, turning up to the first day of school looking super-rad with his blonde locks tucked under a baseball cap emblazoned with his name, an earring in each ear and a black and white "The Future" top.

"Jaxon's first day look. #school," the boys' dad Jeremy proudly tweeted alongside the snap.
