Billie was joined by her family as well as new boyfriend Jesse Rutherford, of Sweater Weather and The Neighbourhood fame, on stage at Inglewood, California's Kia Forum Friday night.
She was performing the final concert of her three Hometown Encore shows, when she was surprised with a cake brought by her brother, fellow musician Finneas, and her boyfriend.
The singer received a wave of applause and cheer from concert goers after blowing out her candles, and she joked she still needed to wait two days until she could drink, noting that it was "[expletive] unbelievable," she would be officially 21.
