ITV's Lorraine was forced to censor Ryan Reynolds during a daytime TV interview after the actor swore live on air.
Host Lorraine Kelly, 62, was interviewing the Deadpool star, 45, remotely to discuss his new time-travelling film The Adam Project when he dropped an expletive.
But while the two chatted over the film, the Hollywood star jokingly described his 13-year-old co-star Walker Scobell as a "b******", forcing the ITV programme to bleep the word out, the Mirror reports.

Lorraine said to Ryan: "I love how you referenced movies like ET and Back to the Future. It has got a lot of heart, but it's funny, it's snappy, it's clever, it's silly and I like that too.”
She then asked: "What about your little co-star? He is a bit of a scene-stealer."
Ryan then cheekily replied: "He is. That cheeky little b******, I'll tell you that much."
In the film, Ryan plays time-travelling fighter pilot Adam Reed, who teams up with his 12-year-old self, played by Walker, for a mission to save the future.
Ryan added: "There's no stopping that kid. He's amazing. We read hundreds and hundreds of kids for that role and I think the second sentence out of Walker's mouth, we knew that he was the guy.
"Not only is he an incredible actor, he's also an incredible mimic. He could mimic my cadence and delivery in ways that were kind of baffling."
Ryan added that "so many things" in the film echo his own life and his relationship with his father, James Chester Reynolds, who died in 2015.
Ryan said: "I had a lot of stories I told myself about him that corroborated my own shortcomings and made excuses for things in my life I didn’t want to confront and the movie really tackles that head on.
"Sometimes those stories aren't necessarily true. I had that moment in my adult life where I asked if that story is really true - somewhere between superhero and supervillain are our parents.
"They're right in the middle. They're human beings doing the best with what they have and that's no exception in my family."
This comes as the actor and his wife Blake Lively promised to donate funds to help support the people of Ukraine in the wake of Russia's attack on the country.
The Hollywood couple have pledged to match donations up to $1 million made to help refugees fleeing their homes.
