Brace Yourself for Adorableness! Justin Bieber Sings Happy Birthday to His Little Brother Jaxon (Video)

justinbieber-jaxon-112013Justin Bieber filmed a music video for his new song “All That Matters” earlier this week and it also happened to be someone very special’s birthday – his little brother Jaxon!

Justin was joined on set by Jaxon, his sister Jazmyn and his dad Jeremy where they sang the new four-year-old happy birthday and enjoyed a cool Power Rangers cake. Things took a turn though when Jeremy decided to have a little fun and put Jaxon’s face in the cake. Lets just say Jaxon wasn’t too happy, but we still find it so adorable. Justin also admitted that his dad did that to him when he was little too.

Watch the cute family moment below. In case you missed it, Justin is featured on the cover of this week’s issue of The Hollywood Reporter. For more, go here.
