Rebel Wilson has been forced to retract a serious of enraged tweets directed at a reporter who she alleges was harassing her “sweet, sick grandma” in a pretty awkward and irresponsible case of mistaken identity.

Yesterday, Mamamia reported Wilson had called out the Features Editor at House & Garden magazine, Elizabeth Wilson (no relation to Rebel), as “total scum” and a “disgrace” for harassing her “sweet, sick grandma”, releasing her photograph to her 2.5 million followers.

After being told by fans that she had targeted the wrong person, the actress and comedian took the photo down, but is yet to publicly apologise to the woman she mistakenly, and very publicly, attacked.

In addition, Wilson is yet to delete a tweet that names Elizabeth Wilson as “disgrace”, and has instead tweeted that she’s “riled up about the situation”.

When Mamamia contacted the woman who Rebel attacked, she said she was “really disstressed” and “gobsmacked” by what had occurred.
