MTV Music Video Awards: Demi Lovato and Iggy Azalea: almost cool. Like any ex-Disney starlet worth her salt, Lovato is trying to sex it up these days, but something about the dominatrix look felt a little forced. Azalea — who, remarkably, has never appeared on the main part of the MTV Awards before — came out and played second banana to Lovato, awkwardly. Together, they indulged in a bit of bumping and grinding that probably wasn’t purposely intended as an homage to Cyrus and Robin Thicke’s 2013 appearance, even though it came off as a pale reenactment. In the end, even with these duet partners trying a little too hard, “Cool for the Summer” still fit in fine with the show’s less prurient, more breezy tone.
