The model, who is engaged to Gladiator star David Mcintosh, admitted to hitting her famous exes in her upcoming autobiography.
One passage read: 'Jason started to swing his hips from side to side and do a little jive with his arms, saying: 'Gywnnie, Gwynnie, Gwynnie. Sexy, sexy, sexy!' He turned round, only to be met with my fist in his face.'
However Twitter users reacted angrily to the 34-year-old laughing about her actions, with one viewer tweeting:
“Disappointed with @itvthismorning for laughing along with Kelly Brook RE her hitting boyfriends in the face! Domestic violence isn't funny!”
Another tweet read:
"Glad she finds domestic abuse so funny! A punch is abuse no matter what gender's doing it', and: 'Would you all be laughing your heads off if it was man giggling about how he punches his partners? Disgrace."
Defending her actions during the interview, Kelly said:
"It's true, I did both of those things. Listen, I'm not saying that I'm an angel and I'm not saying that things I've done are right. But yeah, I guess I get some of that fiery passion from my parents."

She later tweeted: "If I giggle don't judge me... I do it at funerals and when I'm told off too #Nerves."
