Fans who attended 106.1 KISSFM's Fall Ball in Seattle were treated to a surprise when Demi Lovato gave a powerhouse performance of Adele's hit song "Hello." Lovato wowed the sold-out crowd as she hit every note in the difficult song.

The 23-year-old singer dropped her latest album, "Confident," last month and will have the honor of receiving the inaugural "Rulebreaker" award at Billboard's Women in Music event on Dec. 11 in New York. She is receiving the award for being fully in charge of her own career, according to Janice Min, the co-president and chief creative officer of Guggenheim Media's Entertainment Group, which owns Billboard.

"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," Min said. "She's a true force in the industry and a 'rule breaker' who has inspired millions."

The former Disney star is performing at a number of iHeartRadio Jingle Ball concerts over the next couple of weeks before she sets out on a tour with Nick Jonas. The tour is called the "Future Now Tour," and it kicks off on June 24, 2016 in Florida and ends on Sept. 17, 2016 in Los Angeles, E! News reported.
