The 19-year-old singer joined younger sister, Alli, for the relay where they repped Coca-Cola for the games.
“Today was completely surreal!!” Alli reflected on Instagram. “A milestone in a young ones life. To run with the Olympic flame in the official torch relay, day of the opening ceremony.”
She added, “An absolutely breathtaking honor – thank you @cocacola & to anyone & everyone who helped make this possible – my life has changed, this will stay with me forever! I love Brazil ???????? lets go team AUS #thatsgold @rio2016.”
