Former Hollyoaks star Stephanie, who is expecting her first baby, slammed the Twitter user and explained that "vile people" were the reason she would not be sharing any scan or bump pictures.
The male poster jibed: "You're not even pregnant. We're all just waiting for the inevitable 'miscarriage horror' story. You're a mess."
Fighting back, Stephanie blasted: "Absolutely disgusting! This is why I'm not sharing any photo [sic] as there's so many vile people! I've been under enough stress."
Stephanie's followers have been quick to rally round, with one saying: "Having had a miscarriage myself I find the comments disgusting."
Another added: "They are nasty vile people, no matter what people think they should never wish that on anyone. Good on her for pulling him up."
Following her bitter split with former Celebrity Big Brother co-star Jeremy McConnell last month, Stephanie confirmed her pregnancy
Actress Stephanie is insistent that her unborn child is his, while Jeremy maintains it is not.
Speaking to OK magazine, Steph said: "My pregnancy was a shock but I can't wait to be a mum. I hope that Jeremy will want to be a part of this baby's life, but if he decides not to then I am prepared to raise our baby on my own."
Since then, Stephanie has talked about her cravings for gherkins and how she feels she is expecting a baby girl.
