STU Laundy, the pub magnate picked by Bachelorette Sophie Monk as her man, says he fears for his kids' well-being amid an avalanche of criticism the couple has copped.
As a host of radio and TV celebrities continued to queue up to call the validity of the TV program hook-up into question, 44-year-old Laundy flagged the "only concern I have had thus far throughout the entire process".
"That is the well-being of my children and the negative impact on them," he told OK! magazine.
"People's opinions can hurt kids, which I don't think they realise."
The knives were out over the integrity of the relationship before the curtain fell on the series' big finale last Thursday, when viewers learned that Monk had chosen Laundy over vineyard manager Jarrod Woodgate.
Radio personalities Kate Langbroek and Em Rusciano declared the couple's love to be a sham, with Channel Ten's Meshel Laurie piling in on The Project.
KIIS FM's Langbroek was quoted to have said to Laundy: "This is a scam and it will take a lot of convincing for me to believe it."
Langbroek did, however, retweet a Sophie Monk video tweet showing support for the relationship.
Rusciano told listeners this week she thought that Monk had not been honest with Bachelorette audiences.
"I think Sophie Monk has got exactly what she wanted out of this show," she said on air.
"She is a smart businesswoman, wants to be in the entertainment industry and I think she has become Australia's darling.
"I think she has played a trick on everyone and the ultimate prize is a great career, not a man."
Laundy accused Laurie of being rude to him on The Project when the couple faced the Channel Ten panel last week.
Laurie said Monk had done "the classic woman thing" during the series.
She told Monk: "I think you've done the classic woman thing where you say that you want one thing but what you actually go for is something else.
"You said in the beginning 'I just want a down-to-earth, normal guy who wants to get married and have kids' - what you've chosen is a millionaire who's already married and had a vasectomy."
On Tuesday, Laurie retweeted news of refugee calamity on Manus Island with her own reflection: "But by all means, stay focussed on that dating show."
Laundy told Daily Mail Australia: "I understand we've opened ourselves up to scrutiny, dating on a show like this, and yes, Soph is a national treasure, which will raise interest.
"People are entitled to their opinions but I guess I just ask for a chance to prove the non-believers wrong."
