Demi Lovato is Knotty and ‘Confident’ at 2015 iHeart Music Festival

Sporting a 90s throwback tiny top-knot do, Demi Lovato looked all kinds of rock and roll edgy in the outfit she wore on the red carpet when she arrived at this year’s iHeart Music Festival in Las Vegas.

The “Cool for the Summer” singer talked to Billboard about her new album, Confident, which is scheduled to drop on October 16.

I’m not afraid to have attitude on this album and just be able to say what I want, speak what I want — that’s really what I’m most proud of on this album is kind of not caring what anyone else thinks....

For the first day of the iHeart Radio Festival, Lovato took to the stage to perform this summer’s hottest jam, “Cool for the Summer,” along with another one of her hits, “I Really Don’t Care.”

In keeping with the 90s theme, Demi joined Third Eye Blind frontman, Stephan Jenkins, for their take on the band’s hit song, “Jumper.”
