The One Show hosts were forced to apologise after being caught off-guard by a guest swearing TWICE.

The episode got off to a rocky start when presenter Alex Jones revealed her earring had fallen out live on air in front of Ant McPartlin and Dec Donnelly.

Then chaos ensued as Mickey 17 stars Naomi Ackie and Toni Collette ‘performed’ in front of the Geordie duo.

As the Australian actress demonstrated her unique party trick of impersonating a toaster, Toni said: “S**t I can’t believe I’m doing this.”

Alex and her co-host Vernon Kay then rushed to apologise to viewers for the bad language.

“We’ve got to apologise for that, potty mouth Toni,” said Vernon.

However, moments later, Toni repeated the same swear word after refusing to accept it was her.

She shouted: “Did I swear? S***.”

It sent the celebrity guests into hysterics – as Vernon added: “Apologies again.”

Dec held his head in his hands as Ant bent over laughing.

Toni insisted the jet lag she was suffering from had made her badly behave.

Toni said: “I’m jet lagged, I’m out of control

One fan said: “Not Toni Collette saying ‘s***’ twice on #theoneshow.”

Another wrote online: “Toni Collette swearing twice. PMSL…. so funny.”

Toni and Naomi star in a new action sci-fi with dark comedy, mystery and romance, Micky 17.

The film is released in the UK on March 7 starring Robert Pattinson, Steven Yeun and Mark Ruffalo.
