She said she don't like to call herself lesbian, straight or bi. She just likes people.
Actually she wrote the songs for her album based on a relationship she had with a girl. She always made that clear so no, she's not hoping on the "bi" trend.
All new pop girls say they're bisexual when they first become popular. Gaga, Nicki, Jessie, etc...
she had an actual long term relationship with another woman though, and that's who her album was based off of. I believe she is truly one of my queer sisters
