My pal Shawn Mendes visited us the last week and helped me complete the Ice Bucket Challenge by dumping FREEZING COLD ice water over my head...thanks dude... We nominated Shawn's tour-mates The Vamps, Fifth Harmony and Austin Mahone!

 

Well, The Vamps were totally down and accepted our challenge, with a little help from the gorgeous ladies of Fifth Harmony (no big deal)! Watch:

Then Fifth Harmony did it themselves and they nominated Austin too:

 

Check out the original video of Shawn and I completing the #ALSIceBucketChallenge on the streets of NYC:

 

WE'RE ALL WAITING AUSTIN!
