TV chef Gordon Ramsay got the shock of his life when he saw that his daughter was on a date with his mate's son.

The temperamental cook was enjoying a trip across the States in the hit series Gordon, Gino, and Fred: American Road Trip when he discovered Tilly was out for dinner with Gino's son Luciano.

Luciano was out for tea at Heddon Street Kitchen in London, which just so happened to be owned by Ramsay, when he decided to check in with his old man.

Teasing the chefs, Luciano asks his dad and Ramsay: "Do you know who I'm with?"

Holding his phone up so they can both see the screen, the camera then cuts to Tilly, who is enjoying a nice meal with Luciano.

Irked, a pretty surprised Ramsay screeches: "What the hell? Tilly! What are you doing, Matilda?!"

He adds: "You didn't tell me you were going to dinner with Luciano."

To which Tilly then responds smugly: "Oh, sorry. I must have forgot."

Fred Sirieix, who was clearly loving every second of this, with him not having any children involved, then ramps up the awkwardness, saying: "It's OK to kiss on the first date, if you feel the urge, you've got to do it."

Ramsay gasps: "Mamma Mia!"

I mean, you can't blame him, can you? It would be a shock for anyone, even if it was a joke.

Getting slightly more serious, Ramsay and Tilly are clearly incredibly close, with the pair regularly having a laugh on social media together.

But last year, during an appearance on Celebrity Gogglebox, the top chef opened up about the fears he had when Tilly had her brain tumour removed.

The Kitchen Nightmares star said Tilly was just 12 years old when she had a non-cancerous tumour removed. Tilly, who is now 21, had a series of MRI scans when doctors thought she might have had cancer.

The father-daughter duo watched the story of Emily who died at the age of 22 after being diagnosed with cancer.

Ramsay reflected on his daughter’s surgery while watching Emily’s story, saying that he was terrified of what might happen.

He said: “When we found out you had a tumour when you were 12 and that was that horrible period of, is it cancer or is it non-malignant so going into theatre with you... do you remember?"

Tilly nodded, to which he went on: “And it wasn't cancer. F***ing hell.”

She said: “I was very lucky.”
