Demi Lovato Looks Fit and Fierce in Her Bikini, Is Clearly Still Cool For the Summer

Demi Lovato is kicking off her Summer right. On Thursday, the singer donned a bikini for a pool day in Miami; she sunbathed in a lounge chair and spent time in the water. Demi, who recently ended her six-year relationship with Wilmer Valderrama, is right at the beginning of her exciting Future Now Tour with Nick Jonas. We've already seen the duo pop up for a gorgeous joint appearance in NYC, where Demi slayed yet another performance of "Confident." While we're looking ahead to the excitement in the months to come, we're just happy to see Demi squeezing in a little relaxation time — and joining the ranks of all the other hot, bikini-clad stars this year.
