A representative for Ashley Greene has dismissed reports suggesting tensions between the TWILIGHT star and Demi Lovato over Joe Jonas prompted the Disney star to check into rehab.
The 18 year old has pulled the plug on tour dates with ex-boyfriend Joe and his Jonas Brothers bandmates and checked into a treatment centre for "emotional and physical issues she has dealt with for some time."
Reports suggested Lovato was devastated after seeing Joe with new girlfriend Greene backstage at a show over the weekend (30-31Oct10), but the actress' spokesperson has denied the claims.
Greene's rep tells E! News, "There is no truth to this rumour or any other rumours of conflict between the girls."
