The pair were hosting the ITV show together and were talking to a guest about laughter being great medicine and having a lot of health benefits.
The trio had been going through some types of laughter and the impact it had on the body when Peters jumped up and said he wanted to give Humes a giggle.
“I really want to make Rochelle laugh so I am going to stand up,” he said as his co-host looked baffled.
Jumping in front of Humes with his back to the cameras, Peters asked: “Have you got my music ready?
“OK, Rochelle here we go!”
The normal lights were swapped for disco lights and music started playing as Peters jokingly undid his green shirt and flashed his chest as he writhed in front of the star.
Humes looked stunned, exclaiming: “Oh my!”
“This is not what I need to see!” she laughed.
Viewers were also amused by the hilarious moment, with some joking that Peters – who is known for his muscled physique - just wanted to show off his buff body.
“Can someone get Andi a button up shirt, he might keep it on,” one person quipped on Twitter.
“Has Andi increased his days at the gym, wanting to show his body off!” asked another.
Others remarked on how good Peters and Humes were together.
“Absolutely love love love this pair, brilliant and funny making the show so fresh again," said one.
“Andi and Rochelle bring fresh air to the show,” said someone else.
“They need to be the new full time presenters.”
