Demi Lovato Replacement? -- Won't Be Replaced on Jonas Bros Tour

The Jonas Brothers' show must go on ... but it will go on without a replacement for their special guest act Demi Lovato.

A source connected with the tour tells TMZ, "There are no plans to replace Demi for the remaining six days on the Jonas Brothers Live in Concert tour."

As TMZ first reported, Demi decided to leave the tour and seek help for "physical and emotional issues" at a treatment facility.
