He's apparently the third most powerful celebrity on the planet, has 23 million followers on Twitter, and sends fans into a frenzy every time he leaves the house – excited 'Beliebers' recently caused road blocks in Paris.
At just 18-years-old Justin Bieber has the world at his feet.
But this weekend he was upstaged by a member of the next generation of his talented clan, his little brother Jaxon.

The two-and-a-half-year-old tot joined his famous sibling on the red carpet at the MuchMusic Awards in Toronto where he was given his first real taste of showbiz life.
He wrapped his arms around beaming Justin, who proudly carried him inside the event.
And the crowds went crazy for the adorable youngster, who might have been just a little overwhelmed at all the attention.
The warm reception was the start of a great night for Justin, who picked up two awards on his home turf, for International Video for his new single Boyfriend, and Ur Fave Artist.
"Great night here in Canada! Glad to be home," he tweeted during the night. "Got to rock the carpet with my lil bro Jaxo! He killed it."
Justin also tweeted his pride at protégé Caryl Rae Jepsen’s success, having propelled her onto the global stage after he tweeted her song.
She walked away with three accolades, including Video of the Year for her breakout hit, Call Me Maybe.
Katy Perry put in a typically show-stopping appearance.
She managed three costumes changes at the ceremony, arriving in a superhero-esque dress and accompanied by a group of young girls dressed in mini-replicas of previous outfits worn by the star.
She later changed into a spectacular butterfly creation to perform her single, Wide Awake - seemingly a commentary on the break-down of her 14-month marriage to Russell Brand.
The lyrics include the lines: "I was in the dark, I was falling hard with an open heart. How did I read the stars so wrong?
"…Not losing any sleep, I picked up every piece and landed on my feet. Need nothing to complete myself. I am born again, outta the lion's den. I don't have to pretend. The story's over now, the end."
She debuted the song at the Billboard Awards in May with a performance which saw her lowered onto the stage wearing a wedding dress.
Katy took home two awards in Toronto – for Favourite International Artist and International Video of the Year for hit single, Last Friday Night.
