Jake Quickenden has said his girlfriend Sophie Church was told by online trolls to "drown your baby".
The former X Factor star admitted that while he is used to people trolling him, he was shocked that people were targeting his 10-week-old son Leo.
Candidly opening up about the online abuse he and Church have been subjected to since Leo was born, he said: “It hurt, but you have to ask yourself, “Why are people doing this?
“Sophie received one saying, 'Why don’t you drown your baby.'”
He added that “something must change with online laws”.
Quickenden was asked for his "thoughts on trolls" on his Instagram story on Wednesday after he prompted followers to ask him questions as he went on a walk with Leo in a chest harness.
He responded: “Lonely, lacking something in their own lives, jealous probably a bit hurt.
“I feel a bit sorry for them, to be honest."
Previously, just a month after Leo’s birth, Quickenden addressed the horrific extent to which his newborn son was being trolled online.
Posting an image of Leo in a blue, spotty button-down romper suit, he said:
“REAL POST… So in the past week this little man has been told he needs Botox, that he’s ugly as f*** and that he’s weird looking, me myself have also been told stay off social media if you don’t want to be trolled.
“It’s so baffling to me that I should have to stay off social media if I don’t want my four-week-old trolled.
“I don’t mind people giving me s**t, as sad as it is I’ve had to get used to being called “irrelevant“, “ugly“, “attention seeking“ and the list goes on but to troll an innocent child is so wrong and the people doing it seriously need to seek help.”
He added: “I try and be real as possible, but unfortunately there is a dark side of social media and something needs doing about it.”
Quickenden is among many celebrities who have called for a change in the laws surrounding social media, including Katie Price, who has been campaigning for a number of years to have "Harvey's Law" passed.
Named after her son Harvey, who has also been subject to relentless online trolling, the proposed bill would make it illegal to troll or abuse others online.
Price has said Harvey's Law would make trolling a punishable offence and make a registry of known trolls available to the general public.
