The panellist was dressed in a red sequinned mini dress, which barely covered her modesty as she perched on the front of the car.
She was joined by fellow co-host Nadia Sawalha, who had a bit of difficulty climbing onto the vehicle in the hilarious advert for Loose Women's latest competition.
Nadia rolled onto the jeep in a black dress, which was very similar to Kaye's but, she had chosen to cover up a little more by donning a pair of leggings.
As the camera zoomed in on the women frolicking on the car for the advert, viewers certainly got an eyeful as it moved very close to Kaye's thighs.

She wears these terrible knickers and I told her not to wear them today!
When the advert aired on the ITV panel show, the 54-year-old was left red-faced as co-hosts Nadia, Andrea McLean and Saira Khan laughed at her.
She was so mortified by the video that she hit her head on the desk before getting on the floor, and crawling behind Saira's chair.
Nadia, who was in hysterics, shouted: "That's adult viewing! It's all my fault! She wears these terrible knickers and I told her not to wear them today!"
Kaye hit back: "I don't think anyone needed to know that!"
