This is absolutely adorable! What an amazing big brother!
Check out this HIGHlariously sweet footage of Justin Bieber attempting to promote his new flick, Never Say Never 3D, during an interview when his baby sister Jazzy storms the stage (above)!
We LOVE seeing this side of him!
It's easy to forget that he is an insanely popular and well-known performer, but at the end of the day, he's still a teenager who loves his family!
Hopefully his movie will showcase LOTS of footage like this!
