>>11474931Her mom is absolutely obsessed with showbiz, tried to be an actor, sent her kids to performing arts schools, and even kickstarted a really small indie film for her son/Billie's brother to star in.
Anyways, the brother managed to achieve some success and had a couple of fairly major roles on some TV shows. He also had a band that was somewhat popular and went on a big national tour. The entire reason Billie became a thing is because fans of his band made a song on her Soundcloud go semi-viral, which her brother's agent was able to parlay into a record deal. The label she signed with then spent a shitload of money marketing her and bribing Spotify to put her music into their playlists until she became popular for real (a process which took two years)
