Ashley Greene 'never had a problem' with Lovato

Ashley Greene is convinced she'll never escape reports of a rumored feud with Demi Lovato - because Jennifer Aniston is still forced to field questions about her one-time love rival Angelina Jolie.

Last year (10), reports suggested Lovato checked into rehab to deal with emotional and physical issues because she was devastated over her break-up with singer Joe Jonas and couldn't cope with the sight of him romancing then-girlfriend Greene.

The Twilight beauty has now spoken out to set the record straight, insisting there is no real tension between the girls but she'll forever be asked about Lovato - since they fought over the same man.

She tells Allure magazine, "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."
