EAGLE-eyed Love Island fans caught Sophie Piper mocking Molly Smith and Tom Clare.
The islanders discovered just what the public makes of them in a game called "Couple of Sorts" - but Sophie struggled to keep a poker face.
Some of the categories include 'The Hottest Couple', 'The Most Game-playing' and 'The Most Boring'.
However, when it was revealed that Molly and Tom were voted 'The Most Intelligent' couple, Sophie burst out laughing.
After much disagreement over who should go first, second or third, Sophie read the results.
"Third place Arabella and Adam, second place... sorry, I'm laughing at the first place," Sophie grinned.

Second place went to Georgia H and Anton.
Josh erupted: "And I don't know how the f*** these have got here," before Sophie announced that Molly and Tom were voted first.
Luckily, the entire group found the results pretty hilarious, with Molly taking a sit down after laughing so hard.
Josh continued to shout at Tom, completely baffled by the fact that they were voted.

In the Beach Hut, Molly said: "I actually took a step back and was like 'it's not us, allow them to all fight for it, this is not us'" before Tom said: "It must have been me".
Arabella was not impressed when the group didn't choose her to be considered as the 'most intelligent'.
"Do you know what, I feel like I want to back myself," she said.
Toby and Georgia took the hit and stepped down from their spot in third place, and were replaced by Arabella and Adam.
"I want to back myself because I know I am intelligent," Arabella continued.
"I have life experiences. I'm not standing there when I know I have a lot of life experiences," she added.
Molly also took a savage dig at Georgia S and Toby, saying that she's "not learned anything" from either of them.
"I don't mean to sound bad, but I don't feel like I've learned from Toby and G, in the nicest way possible, like I don't," she said.
Fans found the moment that Sophie lost her cool very entertaining.
"The way Sophie was cracking up at Tom & Molly being voted ‘most intelligent couple’ was hilarious," one person wrote.
"Sophie and Josh howling at Molly and Tom getting most intelligent couple, truly speaking for us all," a second added.
This isn't the first time that a challenge has resulted in a bust-up.
