A Channel Ten spokesperson has confirmed to the Daily Mail that the pair had a "respectful" discussion and have made up.
The odd question embarrassed Antoinette and she responded, "it's a playsuit" as she was trying to discuss emojis in a segment about slang words.
"And she’s gonna' be thirsty!" KAK replied.
Fans took to Facebook to accuse the host of slut-shaming and called for Kerri-Anne to "apologise live on air".
"Antoinette, you look gorgeous! Show those pins off I say. KAK should really bite her tongue a little more, or at least filter the thoughts before making a comment," one Studio 10 viewer wrote.
"Maybe KAK should look up the words " Im sorry " and apologise to her co host for that unnecessary comment it was nasty and shows her true colours," another wrote.
