Friends To Enemies! Inside Nick Jonas And Demi Lovato's Shocking Feud: Report

Maybe Demi Lovato is just too "Confident" or perhaps Nick Jonas is just too "Jealous?" Either way, the former BFFs are now at war over their upcoming Summer 2016 tour!

Within the last few weeks as they prepare for the tour, things have gotten "so hostile" between the singers according to a Life & Style magazine source.

"Nick recently laid into her and told her she's phoning it in during rehearsals while he's working his ass off," the source revealed. However, Demi disagrees! "She screamed that he was faking his passion for music and is like a corporation."

During their rehearsals, the source revealed that Demi takes time to text her longtime boyfriend, Wilmer Valderrama. "He rips into her," the source said of Nick's anger while Demi "doesn't think she's doing anything wrong."

Following the 2016 Met Gala, a feud between Nicki Minaj and Demi started and unforunately, the "Chains" singer didn't take Demi's side! "Nick took Nicki's side and now he's been calling Demi an instigator."

"Nick is furious with Demi and she's fed up with him," the insider explained.

Adding, "Their friendship will never survive the tour."
