WATCH: Exclusive Footage of Tegan Marie Preparing to Have Her 'Dream Come True' on Good Morning America
If not, we have behind-the-scenes footage of the starlet's life-changing experience!
Tegan told Sweety High that the whole day was a complete whirlwind.
"When we were backstage Monday morning, I kept asking my friends and family to pinch me to see if it was really happening," she said.
When we asked Tegan what it was like stepping on that stage she said, "Performing on the Good Morning America stage is a dream come true. I am so truly grateful for the opportunity and I had such a wonderful time celebrating the morning with my Sweety High and Radio Disney families, and also everyone at GMA!"
Congrats again, Tegan!
GMA isn't the first big break for this rising star. See her amazing experience at the CMA Music Festival earlier this year in Nashville HERE.
