Love Island fans reckon they've found the 'Kim' Kai Fagan thought he recognised when the Casa Amor bombshells rocked up on Monday.
As Lydia Karakyriakou, 22, made her way into the villa, the PE teacher, 24, looked shocked as he said: "I know her!"
Thinking the brunette was called Kim, Kai shouted: "Kim, Kim", however Lydia sashayed in nonchalantly - unaware she has a doppelganger.
Love Island's Instagram account posted a clip of the video with the caption: "We don't know who Kim is but we hope she's having a lovely day."
But now eagle-eyed fans now think they've found the lady in question after some internet sleuthing.
Viewers think Kim is an air stewardess called Kim Schneider from Manchester - and there's no denying she looks like Lydia.
Kim has a string of glamorous photos on her Instagram account and could easily be mistaken for the brunette bombshell.
Fans now want to Kim to rock up in the villa, predicting Kai's face would be "too funny".
Love Island viewers reckon the PE teacher's relationship with Olivia might be on the rocks before the Casa Amor drama has even kicked off.
Olivia momentarily forgot she was coupled up with Kai, as the new male bombshells arrived in Casa Amor.
As the girls introduced themselves and said who they are coupled up with, the ring girl was on the ropes when she had a momentary memory lapse.
When it was her turn to speak, Olivia said: "I forgot his name... Kai," prompting laughter from the group
She then went on to say that "things are going really well and it will take a lot to turn my head I can't lie", but later told the girls: "I can't believe I forgot his name."
Olivia and Kai were voted one of the least compatible couples in the villa by the public - with neither of them understanding why.
Kai wondered whether he was unpopular with the public as he was surprised Casey and Claudia, who had only known each other for a few days, gained more votes than him and Olivia.
Now viewers think it might be all over for the pair.
One Twitter user said: "I said Olivia's head would turn. She was never into Kai. She already forgot his name and now she's forgotten him."
A second wrote: "I knew Olivia and Kai’s connection was an act."
While a third mused: "We all knew Olivia didn’t like kai."
