The 21-year-old musician tells People, “It’s a dream come true. She was the first girl I ever had a poster on my wall of, and her album was the first CD I ever bought. It’s so funny to think I had that on my wall and here I am about to perform with her.”
Joe added about the tunes he’ll play, “I’ll be playing more music than I have the past few times I’ve performed live so far. It’s going to be really fun to perform some of my music from the album.”
After tomorrow’s performance, Joe will join Britney in Europe with performances in Sweden, Germany, the Netherlands, France, Ireland and the United Kingdom in October.
