While they've been lapping up the sun with swimming and cocktails, fans noticed one hilarious detail in a snap of the happy couple swimming at the beach.
The photo shows Karl smiling with his wife Jasmine at the Kokomo Private Island Resort. In the caption, Karl wrote: "This woman is seriously punching above her weight."
The TV star however had clearly not lost his sense of humour and was posing for the snap with his goggles on upside down, a detail many fans were quick to point out.
"Could be wrong but am thinking those goggles are upside down. She really is punching," one joked.
"Yo Karl, can you see better with upside-down goggles?" another said.
"How did she score him?" a third quipped while a fan commented, "Someone’s punching and I’m pretty sure it’s not Jasmine".
Others called him a "dag" and a "clown" for the hilarious Instagram snap.
"You are such a legend," a fan wrote.
"Gorgeous couple," another commented.
It's not the first time Karl has entertained fans with his hilarious holiday photos, with Jasmine sharing a snap of him posing in their daughter's goggles while on a plane earlier this year.
The TV host is wearing a face mask and holding his hand in a peace sign while his eyes are framed by his daughter's Peppa Pig swimming goggles.
"Even Harper looks bemused," one commented.
"It's a vibe," another said.
"Soo funny," a fan added.
