Justin Bieber Celebrates Little Brother Jaxon's Birthday: Watch Here!

Showing his softer, gentler side, Justin Bieber helped celebrate his little brother”s 4-year-old birthday earlier this week.

Lovingly singing “Happy Birthday” to adorable Jaxon, the Biebs plopped him in front of his cake where his father Jeremy then pushed the boy”s face into the pastry.

Unfortunately, the light-hearted prank was not appreciated and after many tears, things finally calmed down as Jaxon and his sister Jazmyn took turns putting their faces in the cake on their own.

Sharing a link to the video, Justin tweeted, “This is what it is all about. Family. #happybirthdayJaxon and yeah he did it to me too. Lol.”
