Nick Knowles said he was 'raging' after internet trolls started posting negative comments about his girlfriend - who is 26 years younger than him.
The Who Dares Wins presenter, 59, and his ladylove, Katie Dadzie, were recently pictured strolling and kissing through London's Mayfair after enjoying a romantic dinner.
The pair were first linked in August last year after DIY SOS star Nick met the young mum-of-two at a kids’ group attended by his youngest son.
Taking to his Twitter, Nick hit back at those who had criticised Katie as he boasted about how she "runs three businesses" and is "wealthier and more successful than me".
He Tweeted on Wednesday night: "I’m raging The woman I was out to dinner with when we were papped is 32, has degrees in two subjects, runs 3 businesses, is a mother of 2, is wealthier & more successful than me & is intelligent & independent unlike the abusive trolls attacking her.
"What happened to #bekind?"
Fans took to the comment section to support the presenter.
"Unfortunately people will be people and it will be someone else’s turn today," one user said.
"I’m sure she is a very nice person and you both should be able to go out without negative comments your lives are yours and know one else’s. This is why I prefer Cats and Dogs."
Another tried to keep things light and said: "What did you have to eat?" to which Nick responded: "Japanese food - was lovely."
"This young lady sounds amazing and a real asset to the world!" one user complimented his girlfriend.
"I can’t imagine what the “trolls” would be saying about her that warrants any attention! I wonder if they do actually ever look at themselves and are happy with what they see."
