The 38-year-old gave her 931,000 followers a glimpse of her red and pink frock as she danced in the studio ahead of a chat with her fellow Loose Women panellists.
Kelly clung on to her figure-hugging dress as she moved her feet from side to side, beaming a smile for the video.
She captioned the clip: “I’m Loose”.
During the ITV show, Kelly made a controversial comment about working mums, which didn’t go down well with many of its viewers.
Kelly confessed her dislike for mothers using their children as an “excuse” to cancel prior commitments.
She said: “I have a pet hate, and I don’t have children so I don’t always understand.
“But I do work with some women that if they can’t make an appointment or can’t do something, or there is a deadline, some people will always say, ‘Oh, it’s because I have to wash the baby’ or ‘feed the kids’ or ‘I’ve got to do the school run’.”
Many Loose Women fans flocked to Twitter to slam the star for her views.
One unimpressed user commented: “Kelly the expert in trying to be a parent and juggle a career. How many kids does she have again?”
Another sarcastically added “Ah. The childless Kelly Brook giving advice to working parents.”
Kelly was quick to respond to the controversy on her Twitter page.
In a now-deleted Tweet, she hit back explaining it was not her “intention” to offend anyone.
“It’s a debate show so I don’t expect everyone to agree with my options and that’s OK @loosewomen,” she told her one million followers.
“However, my intention is never to upset anyone.
“I work with a lot of working mamas and they are all professional amazing women and never moan,” she added. “They get on with it. I applaud them.”
After the show, Kelly put on a loved-up display with her boyfriend Jeremy Parisi, 32.
The Italian model took over camera duties as Kelly cosied up to her man for a selfie.
Jeremy, 32, gave a blank expression in the snap, while Kelly flashed a smile.
She captioned the picture: “My Angel”.
Many of her social media fans were quick to compliment the cute duo, who have been in a relationship since since 2015.
One user wrote: “Lucky guy,” while another commented: “Beautiful couple.”
