Demi Lovato Is Taking Ariana Grande's Spot at a Big-Shot Concert

Ariana Grande has called off her performance at the Major League Baseball All-Star Concert on July 11 in Cincinnati, and Demi Lovato is replacing her. Ariana's appearance cancellation comes right after a bizarre video of the singer licking doughnuts and saying "I hate America" at a shop in in Lake Elsinore, CA, went viral, but it's not related to the controversy. The reason preventing Ariana from performing: she recently had three wisdom teeth removed. Demi, who is promoting her new single, "Cool For the Summer," is taking her place and headlining the concert, and if her recent sexy performances are any indication of the show she'll give, the audience won't be disappointed.
