Demi Lovato Reportedly Fires Longtime Manager

Weeks after confessing her relapse on new single "Sober," Demi Lovato has reportedly fired her longtime manager, Phil McIntyre.

RadarOnline.com says the pop star "dumped" her manager "in the middle of her tour."

"She wanted to go in a different direction, and decided to completely severe ties with him," a source told the tabloid, adding that Lovato is "focused on surrounding herself with positivity and accountability."

Neither Lovato nor McIntyre have acknowledged the rumors of their split.

It's believed that the singer also cut ties with her rehabilitation and recovery business, CAST Center.

"They are in a bitter dispute over money and branding," a source told Radar.

In June, Lovato released "Sober," a heartbreaking track featuring lyrics that seemed to confirm that she had relapsed after six years of sobriety.
