Halsey is playing herself in "A Star is Born."
She made the reveal on Twitter and thanked Bradley Cooper and Lady Gaga for including her in the movie:
I guess now is a good time to finally tell you guys that I have a little cameo in A Star Is Born! Thank you so so much to Gaga and Bradley for including me. It was an honor to watch both of your talent and dedication on set. ❤️ an all time life highlight for me for sure.— h (@halsey) September 5, 2018
I play myself for a very small moment! Which is insane because it means Gaga and Bradley saw me worthy of representing a piece of the current state of music in this film forever. They could have picked any artist. It was so humbling and unreal. https://t.co/GnLTIydTX6— h (@halsey) September 5, 2018
