Love Island fans spotted Gemma Owen's angry face as she dubbed new bombshell Ekin-Su as "patronising".
The pair came to a war of words during tonight's show as newbie Ekin-Su focused all of her attention on Gemma's partner Davide Sanclimenti just moments after joining the ITV2 show.
Gemma was originally coupled up with Liam Llewellyn but they soon split up as Davide set his sights of the international dressage rider. However, their romance seems at risk as Ekin-Su has made it her mission to get Davide.
In scenes airing on tonight's show, she flirted with Davide - making him and the other boys some eggs.
But it was her flirting with Davide in front of Gemma that left the equestrian fuming.
As the girls were welcomed into the villa, Davide and Ekin-Su started chatting about the gym, as the actress - who hails from Essex - questioned whether he was going to do a gym session with her sometime.
An angry Gemma watched on, but things got even worse when Ekin-Su called her her "baby sister". The group were discussing ages, and when Gemma admitted she was 19, Ekin-Su called her young but Gemma took issue with her comment.
Once she'd gone, Gemma fumed over the comment and dubbed her "patronising", as the girls snuck up to the balcony to secretly spy on the rest of the villa as newbies Ekin-Su and Afia made eggs for the boys.
Gemma admitted earlier in the episode she was feeling a bit worried about Davide, as she added: "I am confident in myself. I know what I want and nine times out of ten, I do get what I want but this could be the one time difference."
As Amber Beckford shared: "I am still happy to get to know them, I am not going to be a b*tch, but be a b*tch to me and you ain’t gonna get the nice Amber, a storm is about to begin."
Davide clearly took a shine straight away to Ekin-Su and Afia.
"Wow, wow, wow - the two new girls are fire," he said, as Luca admitted he had eyes for Ekin-Su.
He shared: "Ekin-Su, oh my god, she's going to cause trouble."
