Gordon Ramsay left The One Show viewers very amused as he swore live on the BBC series on Thursday night, while the show's hosts did not look impressed.
The chef and TV star joined singer Michael Bublé on the show, alongside hosts Alex Jones and Rylan Clark.
Michael discussed his new album and single, while Gordon revealed all on his latest TV venture.
As the show was drawing to an end, Rylan thought he heard Gordon swear and laughed it off - only for him to actually swear.
Gordon dropped the s-bomb leaving the presenters a little flustered as they carried on with the show without mentioning it, as Gordon and Michael looked very amused.
It all happened as Rylan and Alex quizzed the guest over a romantic comedy movie Gordon once appeared in, leaving him embarrassed.
Gordon responded that the film was terrible, saying: "It was a nightmare. It was just a shocker."
Rylan confessed he thought he was going to swear, adding: "I wondered what you were gonna say then!"
It's then that Gordon said: "No I was s**t, I was sugar, and sweet and just bad," as someone was heard making a noise out of awkwardness.
As the hosts tried to ignore what happened, viewers at home asked what they were expecting given Gordon is famous for his expletives on TV.
One viewer tweeted: "Of course Gordon couldn't go half an hour without swearing."
Another said: "Haha 'crap' and 's**t' said before the Watershed?" as a third added: "Alex will be mortified, Ramsay saying s**t on the one show."
A fourth viewer tweeted: "How can they expect @GordonRamsay to not swear on live tv," and a fifth said: "Wee swear word there from Gordon."
Viewers loved the episode, and couldn't help but laugh along with guests Gordon and Michael as they joked around.
"All the doom and gloom around at the moment @GordonRamsay and @MichaelBuble were great fun guests. The chemistry between Alex and Rylan very noticeable too," one fan tweeted.
Another said: "What a great show tonight, great to see @GordonRamsay and Michael Buble having such a laugh."
A third agreed: "Michael Buble and Gordon Ramsey on The One Show. So funny how they haven’t stopped laughing at themselves and each other! Loved it."
The One Show airs weeknights at 7pm on BBC One.
