BBC Breakfast star Nina Warhurst left morning TV viewers covering their ears after a very rude slip of the tongue this morning.
Jon Kay and Sally Nugent were on main hosting duties on the iconic red sofa but it was Nina, 43, who stole the show during her live money and business report.
Nina was there to discuss the ups and downs of the budget but ended up accidentally swearing live on air.
Introducing the segment, Jon said: "Let's talk about the budget next week and there is a warning this morning that the Chancellor should not cut taxes.
"The warning comes from a leading think tank, Nina can tell us more - morning Nina!"
Nina was then left gritting her teeth as she accidentally dropped the C-bomb just seconds into her opening line.

The broadcaster said: "Thanks Jon, yeah, when tax c****..."
Nina quickly attempted to correct herself as she said the word "cuts" more clearly as she continued her sentence.
In full, she said: "When tax c****, cuts are announced, the public listens which is possibly why the Chancellor has hinted at this ahead of the budget."
The very sweary moment left fans gasping as they raced to X/Twitter to discuss Nina's embarrassing slip.

One viewer said: "Oops #NinaWarhurst didn’t hold back, just said tax c**** instead of cuts - brightened my day."
Another added: "I do believe Nina just slipped an extra 'n' into 'tax cuts'."
Someone else was so shocked, they watched it twice to check if she had actually dropped the explicit word.
They said: "Oh yeah we rewound it....she definitely said tax c****."
A fourth insisted: "I nearly fell off my chair when she said it!"
Before a fifth penned: "Nina on the #bbcbreakfast taking about tax c****."
It isn't the first time Nina has had an embarrassing moment live on air as the star suffered a mortifying blunder just weeks ago.
Nina was handing back to the main hosts, Sally Nugent and Ben Thompson following another live report.

But she was left cringing at herself as she said: "Now back to Jon and – Ben and Sally. Not Jon, sorry.”
Ben - who has been standing in for Jon Kay that week - chuckled and replied: "Don’t worry, I’ll let you off. Thanks Nina.”
