Gemma Atkinson, 34, who shares daughter Mia with Gorka Marquez, 28, told Gethan Jones, 41, he had left her crying for a third time after he shared the touching video with his 138,000 Twitter followers.
Within the clip, actor Richard Mylan, 46, discusses raising his autistic son Jaco, 11.
He told fans he noticed an improvement in the way Jaco reacts in social situations after using noise-cancelling headphones.
Richard added Jaco could now cope better with everyday noises, but said he was worried they might “cut him off” from the world.
Alongside clips of him and his son enjoying days out together, he also reflected on the first time he told people his son had Autism, claiming they didn’t understand.
He went on to say people have thought he was “deluded” about his son.
Gethin – who has a nephew with Autism – shared the video in view of his 138,000 followers.
He wrote: “Far from deluded. Parents of children who face these challenges are heroes to me.
“We need to buck up our attitudes and let Jaco and others live their fullest life in society.
“And I really hope his home, one day, has a black washing machine. #AutismAwareness.”
Gemma reacted to the video in view of her 270,000 followers, writing: “That’s the 3rd time since knowing you that you’ve made me cry with videos,” followed by a crying emoji.
She added: “At least this time I’m at home and not sat on a packed out rush hour train!”
Last week, Gemma Atkinson gave her own honest insight into being a first time mum.
In view of her one million followers, the radio host filmed herself spending some time with her dog Ollie while Mia was asleep.
As she hugged her pet pooch, she said to the camera: “Mia is asleep and Norman [her other dog] is down the stairs, so I’m having a bit of one-on-one with Olly Bolly, because I don’t want him to feel left out and I think he has done a little bit today.”
She then cosied up to Ollie and gave him a kiss before adding, “you don’t need to though.”
Gemma captioned the clip: “Mia was at her 1st clinic today so it was all a bit mad and hectic and Ollie felt a tad left out.”
The former Strictly Come Dancing finalist followed up her post with a clip of her cradling her baby.
“So we had that long-awaited night where baby didn’t want to sleep,” she said to the camera, before turning to her baby, adding: “Did you?
“You just wanted to chill and make funny little noises like a T-Rex with your eyes open, having a little play for almost four hours.”
Gemma concluded her post with the words: “Papa’s is home tonight so be awake all you like. @Gorka_Marquez is on the night feeds. #SorryGorks.”
