Demi returned in 2015 hotter than ever with the hit single "Cool For The Summer."

Demi slayed the MTV VMAs with bestie Iggy Azalea.

She broke into the tech world with a mobile game, 'Demi Lovato: Path to Fame!'

In October, Demi dropped 'Confident,' her most critically-acclaimed album to date.

We all enjoyed watching DD kick ass in the video for her second single, "Confident."

Continuing her "Confident" theme, Demi posed for a make-up free and Photoshop free 'Vanity Fair' shoot.

Pop wishes were granted when Demi announced she'd be teaming up with BFF Nick Jonas for the Future Now Tour.

Then she lived out every '90s girl power baby's dream by performing with icon Alanis Morissette at the 2015 AMAs.
