Gordon Ramsay has revealed his daughter Tilly is dating Gino D'Acampo's son Luciano.
The two celebrity chefs have teamed up for a new show and as a result their children, both 17, have become close.
Ramsay discussed the romance while appearing on The Jonathan Ross Show, joking it was a “f***ing nightmare”.
The Hell’s Kitchen star said: "We were driving through San Francisco and FaceTiming Luciano, and all of a sudden Tilly pops up behind them, and they are out having lunch.
"I think they are friends."
Ross teased: "I have heard they are more than friends... Is this an arranged marriage we are looking at?”
He then teased Ramsay about 43-year-old This Morning star D’Acampo becoming Tilly’s father-in-law.
The interviewer later quipped it was the “uniting of two dynasties”.
Tilly - who has folllowed in her father’s footsteps as a celebrity chef and has her own CBBC show Matilda and the Ramsay Bunch - is also friends with David and Victoria Beckham’s son Romeo.
Ramsay and D’Acampo - who famously cooked and ate a rat during his appearance on I’m A Celebrity... Get Me Out Of Here! in 2009 - have teamed up for a new TV series with First Dates star Fred Sirieix titled Men Behaving Badly.
