Fifth Harmony is still on cloud nine after hitting the stage with Taylor Swift on the Santa Clara, California, stop of her 1989 tour.
"It was amazing! It was honestly -- it was a dream come true," 5H's Camila Cabello gushed to ET on Sunday's Teen Choice Awards red carpet. “Sixty-five thousand people in the stadium -- and she learned the choreography, wore our tour outfit -- it was seriously a night we'll never forget."
Swift Instagrammed about about being "twinzies" with the girl group over the weekend and "cuddling" on-stage with pals Cabello and Ally Brooke. The girls all donned matching blue costumes for their performance of Fifth Harmony's hit single, "Worth It," on Friday.
