Lovato, Lady Gaga, Selena Gomez and Brittany Howard will all perform at the event.
Demi Lovato will be honored with the inaugural "Rulebreaker" award at Billboard's Women in Music event on Dec. 11 at Cipriani Midtown in New York. This year's Women in Music event will air on TV for the first time via Lifetime on Dec. 18.
In addition to the "Rulebreaker" award, the "Confident" singer will perform at the 2015 Women in Music event.
"Demi Lovato is an artist in full control of her career," said Janice Min, co-president and chief creative officer of Guggenheim Media’s Entertainment Group, which consists of Billboard and The Hollywood Reporter. "Her ability to use and not hide her personal story in her music and in her own mission is inspiring. She has a passion and drive to empower other girls and women that is remarkable. She’s a true force in the industry and a ‘rule breaker’ who has inspired millions."
