Carrie Bickmore's delightful big breast blunder

CARRIE Bickmore's delightful reaction to her own Big Breast blunder shows why she is so popular on Australian television.

The Project co-host was signing off after Monday night's show when she accidentally referred to the Big Bash League as the "big breast".

She was clearly left mortified after the gaffe which Daniel MacPherson later dubbed "breastgate".

"Adelaide, we will leave you here. You're going off to watch the big breast," Bickmore said, clearly stunned by what had just come out of her  mouth.

Co-hosts Peter Helliar and Daniel MacPherson struggled to maintain their composure.

Bickmore later explained she was trying to say that Adelaide viewers with off to the Big Bash coverage while the rest of the nation stayed with The Project.

Helliar said the rest of Australia was asking why they couldn't watch the Big Breast coverage.

The mother of two was labelled a national treasure on Twitter after her reaction to the bungle in the first show of the 2016 season.
