This is definitely NOT cool for the summer!
According to sources, Adam Lambert was supposed to open for Demi Lovato on her soon-to-be-announced upcoming world tour.
We are told that the songstress and the Ghost Town artist already hashed out details such as lighting, billing, and most importantly, money!

However, Miz Lovato's manager had eyes on another pop star…
His own client Nick Jonas!
Insiders say her reps convinced her to swap out Lambert for the Levels hottie, and not surprisingly, Adam is FURIOUS!
According to a source close to the American Idol alum, the decision was :
"very unprofessional and unethical."
Understandably, the 33-year-old feels betrayed and exchanged harsh words with Demi's people.
The 23-year-old diva was supposed to announce her concert last week, but didn't due to this switch-up.
We just hope this drama gets sorted out!
