Daughter of celebrity chef Gordon Ramsay, Tilly took to Instagram to share a clip from Steve Allen's radio show and reminded everyone to be kind and to avoid body-shaming.
Steve is heard saying in the clip: "Tilly Ramsay is on Celebrity MasterChef Australia, is she? Well she can't blooming well dance, I'm bored with her already.
"She's a chubby little thing, isn't she? Have you noticed? Probably her dad's cooking I should imagine."
"Steve please feel free voice your opinions however I draw the line at commenting on my appearance. It's such a shame that someone is trying to make such a positive experience negative.
"This isn't the first and definitely won't be the last comment made about my appearance and I accept that and I'm learning to accept myself.
"But please remember that words can hurt and at the end of the day I am only 19 and I'm so grateful for all the amazing opportunities I have been able to take part in and I understand that being in the public eye obviously comes with it's own repercussions and I've been aware of this from a young age.
"However I won't tolerate people that think it's okay to publicly comment and scrutinise anyone's weight and appearance. Love Tilly xx"
On Twitter, Jason furiously penned: "I see that bitter old p***k @steveallenshow is trying stay relevant again, this time by criticising a teenage girls’ body on his shit radio show.
"I’d love to see Tilly’s Dad rock up at LBC and give this troll the tongue lashing he deserves. Awful man, terrible outdated broadcaster."
Meanwhile, Dr Alex shared a screenshot of an open letter he wrote on his Instagram.
"Dear LBC Radio, I hope this letter finds you well," he began. "I am writing to you in my capacity as Youth Mental Health Ambassador regarding the comments made by your presenter Steve Allen, on LBC Radio this morning.
"I am absolutely horrified by these remarks. It is widely recognised just how damaging such comments about someone's weight are and the effect they can have on an individual's mental health. We must not only think of the effect on Tilly here, which I can imagine could be significant, but also the potential impact to listeners of the show.

"I am sure LBC, and Global as a whole, do not condone such comments. We are currently seeing a rise in the prevalence of eating disorders, with up to 3.4million people in the UK currently being affected. We must not underestimate the impact such remarks can have, feeding into the perpetual cycle of weight stigma that stills exists here in the UK."
Dr Alex concluded: "The reiterate, the discussion highlighted above about a young person's weight live on air is not acceptable."
The former Love Island star also shared a personal message to Tilly, writing: "This is absolutely disgraceful. No one should take cheap shots about someone’s weight. No one has the right to comment on your body Tilly. You are a beautiful, kind, talented, courageous and warm person @tillyramsay.
"DO NOT change or listen to horrible people like this. Fair play to you for being so brave and standing up to bullies."
