The star appeared in a VT from Cannes, alongside Strictly Come Dancing winner Ore Oduba and his wife Portia.
The married couple are currently reporting live from the Cannes Film Festival for This Morning.
Wanting to know what was happening at the parties in Cannes, Ore tasked Jean with revealing everything that he knew.
However, the businessman refused to give anything away when he told the TV presenter: “I can only tell you what’s official.

“I’m like a doctor, I cannot talk about my clients. Everything remains confidential.”
Jean-Bernard’s appearance was confirmed on This Morning’s official Twitter account on Wednesday morning.
Retweeting a picture Ore had posted on his own page, news of JB’s interview was revealed.
Ore had shared a snap of himself, Portia and Jean-Bernard.
He wrote alongside the picture: “A scholar and a gent… AND he makes a great cocktail.”
The 31 year old then added the hashtag: “#versinimartini”

French businessman Jean-Bernard, who married Cheryl in 2014, owns a pop-up restaurant in Cannes called Versini.
He is also celebrating the tenth anniversary of his other pop up, Cosy Box, at this year’s Cannes film festival.
It was thought that new mum Cheryl would be attending the festival this year.
The Girls Aloud star is normally a regular at the events’ red carpets through her work as a L’Oreal Paris ambassador.
But this year Cheryl, who welcomed baby Bear with boyfriend Liam Payne in March, will skip the prestigious festival.
A spokesperson for L’Oreal Paris told MailOnline: “Having only given birth less than one month ago, Cheryl will not be attending Cannes Film Festival 2017 with L’Oreal Paris.”

A separate source added: “Cheryl only gave birth last month so understandably it is too soon for her to return to work.
“Cheryl has always attended Cannes with L’Oreal Paris in her role as spokesmodel but there is no way she is going to leave the country with a new born baby.
“L’Oreal Paris are incredibly supportive of her decision.”
The former X Factor judge has attended every Cannes Film Festival since 2010 and last year, the festival was the first red carpet appearance she made since going public with her relationship with Liam.
