Hey Zac,
Just wanted to wish you a very happy birthday
Can’t believe how fast you are growing up and how much you have brought to all your fans who love you so much. Not long and you can drink in America. But have one on me.

I would like to wish a Happy 20th Birthday to Zac straight from Newfoundland. May he have lots of fun (but not too much ) on his day. I turned 20 on July 27th so I already know what a blast it is to finally be out of our 'teens'. Best of Luck Zac man.

You're getting old! Congratz on hitting the big 20, one more year and you're old enough to "legally" drink. I hope you have an awesome birthday, you only turn 20 once so enjoy it to the max. I hope you get everything you wanted because I am sure you desrve it after all the hard work you have done. Keep using your gift of music to make the rest of the world be in a bliss, like i know I am. Happy birthday again and take care!
Always,
