Justin Bieber's adorable half-siblings, Jazmyn and Jaxon, obviously look up to their big brother, as evidenced by this tape of the two of them -- as well as another super-cute pal -- singing his 2010 hit "Baby." Justin's dad, Jeremy Bieber, shared the footage on Vine on Tuesday.
Justin has always been close with 7-year-old Jazymyn and 4-year-old Jaxon, continuously sharing pictures of them spending time together. In May, the 21-year-old superstar Instagrammed this sweet picture of him cuddling with Jaxon.
"Love you more than anything Jaxon," he wrote.
And here's Justin, Jazmyn and Jaxon all making funny faces together.
