Justin Barona on Instagram: "Avril Lavigne - Complicated This was for Caits Birthday! @caiterrs Happy birthday and thank you so much for rocking with me all the way in the Uk. I was so excited to sing this classic song by the emo pop legend Avril Lavigne for you. It’s so exciting to know you are from the UL because in short time I will be announcing a tour and show dates there which I am so excited about. When I do, I’m throwing this on the set list. Happy Birthday God Bless "
