We want to wish a very happy 4th birthday to Justin Bieber’s sister Jazzy Bieber! We hope Justin was able to celebrate with his little sis before heading off on his tour around the world to promote “Believe.”

Justin also has a little brother named Jaxon who turned 2 recently! Do you think Justin will have even more brothers and sisters in the future? His mom has revealed that she would love another kid – aww!

Happy Birthday Jazzy!
