The annual awards show also features performances from MAGIC! who plays their hit single 'Rude' and Rixton who sings 'Wait on Me' and 'Me and My Broken Heart'.
Demi Lovato was among musicians who took the stage of the 2014 Teen Choice Awards at the Shrine Auditorium in Los Angeles on Sunday night, August 10. She kicked off the festivities with a super energetic performance of her newest single, "I Really Don't Care".
Donning an all-black outfit, a black leather jacket and a pair of boots, the former Disney star was joined onstage by a number of dancers who were also clad in black. Mid-song, collaborator Cher Lloyd appeared on the stage to spit her verses.
Later at the event, Canadian band MAGIC! performed their smashing hit "Rude" while numerous people in the audience sang along and danced to the song, which is currently spending its fourth week at No. 1 on Billboard 100.
Also rocking the TCAs were Rixton who started their set with "Wait on Me" before tackling their bigger hit "Me and My Broken Heart" and Becky G who sang her new single "Shower". Jason Derulo then brought this year's show to a close with "Wiggle" and "Talk Dirty".
