Was there beef between Demi Lovato & Ashley Greene?

Demi Lovato and Ashley Greene both have something in common…Joe Jonas, but was there fighting between the girls which lead Demi to fight with a back up dancer, hurt herself and have an eating disorder…people say yes! Not that all of Demi’s problems come from her breakup with Joe , but it seems to be a catalyst in her downward spiral. It has to be hard for her to see her ex-boyfriend and tour mate move forward after their split and into the arms of a new girl…very quickly after.

According to E!,

According to reps for Ashley Greene and Demi Lovato, there was no “Greene effect” on the Disney star’s recent breakdown.

“There is no truth to this rumor or any other rumors of conflict between the girls,” Ash’s publicist tells E! News. Lovato’s rep echoes similar sentiments.

Funny, ‘cause we have multiple sources who witnessed the heated exchange of words, starting from Demi’s end.

But reps never fib—or cover stuff up—so we’re sure D and A are totally BFFs.

Fact is, Ash being in South America with Joe Jonas was probably just the breaking point for Demi. That, and a scuffle with a back-up dancer who was also in the airport in Peru—but that was over stuff entirely unrelated to the Twilight star.
