Selena Gomez + Bahari

Filled with steamy songs, Gomez’s 2015 album Revival was a less-than-subtle announcement that the former Barney & Friends star is entering adulthood. A similarly provocative, Madonna-inspired arena show from the pop star (and former Justin Bieber flame) seems almost guaranteed. Alt-pop trio Bahari—best known for contributing vocals to Zedd's "Addicted to a Memory"—open the show.
