This is not the first time Kym has been sent disturbing messages. Last year, she and fellow Corrie star Jennie McAlpine, 30, were targeted by 'deluded fan' 74-year-old David Watson.

David allegedly sent Kym and Jennie pornographic images, and she also received taunting messages about her son Archie, who was stillborn in 2009.
