Sonia Kruger was left mortified on Tuesday morning after she made an X-rated gaffe live on-air during an appearance on The Morning Show.
The 55-year-old was giving her sister Debbie, who is a hairdresser, a plug after getting her hair styled by her when she was working on the network’s new show Holey Moley in Queensland.
But she hilariously misspoke, leaving co-hosts Kylie Gillies and Larry Emdur and the entire studio in hysterics.
“My sister's a hairdresser, so if you're looking for a good blow job... blow wave,” she was quick to correct herself but the damage had been done.
“In America they call it a blow out. I think that's what I just had, a blow out,” Sonia added trying to explain the mishap, growing increasingly red in the face.
“Lucky we're not live, they'll probably cut that out!” Larry joked, before adding: “I tell you what, your sister's just been booked out for months!”
Big Brother was brought back after it was axed from rival network Channel 10 six years ago in 2014.
