If You Love the '90s, You'll Love Demi Lovato's iHeartRadio Music Festival Look

Demi Lovato kicked off the iHeartRadio Music Festival in Las Vegas, keeping up her cool-girl vibe among artists like Kanye West, Sam Smith, and BFF Nick Jonas. The singer first rocked the MGM Grand Garden Arena in a preshow interview with Z100's Elvis Duran.

During her energetic performance, Demi perform her new single, "Confident," live for the first time, plus everyone's Summer jam "Cool For the Summer", even paying homage to the '90s (again!) with a special performance of "Jumper" by Third Eye Blind alongside the band's lead singer Stephen Jenkins.
