Justin Bieber took some time in between takes on the set of his music video for All That Matters to help his little brother Jaxon celebrate his 4th birthday. The video starts out really cute with Justin carrying his little brother toward his birthday cake while everyone sings Happy Birthday To You to the happy little dude. After he blows out his candles, tho, all of the Biebers (including dad Jeremy and sister Jazmyn) gather together for a photo and then … ugh … Jeremey Bieber turns into an asshole and makes Jaxon cry in front of the cameras ON HIS BIRTHDAY! EVEN WORSE, daddy Jeremy is the one who decided to share this video with the world! Check out the video above to see for yourselves. The video stars out really cute and then the douchebag dad goes and ruins all the fun. Happy Birthday, Jaxon. Sorry your dad is a dick.
