Many devoted Demi Lovato fans turned on Ashley Greene when the starlet started dating Demi's ex Joe Jonas, some even insinuating that she had caused Demi's visit to rehab, but the actress is adamant that this isn't the case.

In a recent interview with Allure magazine (via contactmusic.com), Ash tries to dispel any rumours of a feud between herself and Demi, but knows that the hushed rumours will probably follow her around constantly.  

"I'm really happy that she's (Lovato is) doing well. She and I never had a problem with each other, but, you know, it doesn't go away....Jen Aniston still gets asked about Angelina Jolie."

Ouch!
