A Great Big World’s breakout hit “Say Something” featuring Christina Aguilera has catapulted the duo into stardom and onto the charts.

And they have Christina to thank for more than just the collaboration.

After performing at the AMAs the threesome got into quite a battle. With paintballs that is.

Christina invited the guys back to her house after the award show so they could get to know one another better and they engaged in a full on paintball battle right in Christina’s backyard.

Talk about quite the after party!
