Evans's manager Danny Zargoridis spoke out after the page began posting comments claiming to be from the actress about the current sex tape scandal surrounding her former co-star and ex-boyfriend Lincoln Lewis.
"She doesn't have a Twitter site or a Facebook page or MySpace page, it was not her," he told Australian newspaper The Daily Telegraph.
On Sunday, the Twitter page, which has since been shut down, began posting tweets about the sex tape controversy, with the first saying: "All the Home and Away sex tape stuff affects me too, he is my ex! He didn't do anything wrong guys!"
Another post read: "Everyone should mind their own business. Everyone makes mistakes."
While denying that the page belonged to Evans, Zargoridis refused to comment on speculation that his client is the unidentified TV starlet in the clip, which was filmed on Lewis's phone before being shown to fellow Home and Away cast and crew.
