Love Island twins Eve and Jess Gale showed their fiery relationship when they both wanted to couple up with the same boy in Monday night's episode.
And now last year's Islander Molly-Mae Hague is convinced that the duo will turn on each other as the competition heats up.
Eve told Jess that she wanted to choose Mike, but they bickered when her twin said she had set her sights on the same guy.
Speaking on her YouTube channel, Molly-Mae commented: "Obviously they're going to argue, they're sisters. If you put me and my sister in the Love Island villa together we'd literally pull each other's hair out.
"My extensions would be on the floor.
"Obviously they're going to literally kill each other."
During the coupling up ceremony last night Eve got to go with Mike and Jess took her second choice Callum.
Their decisions didn't go down well with Shaughna and Leanne, who had been coupled up with them first.
And the drama only continues in tonight's episode as they confront the twins about their decisions.
In a teaser clip the girls appear to be sitting around discussing what happened the night before.
Shaughna looks fuming and Eve asks her "are you done?".
Last night Eve was mocked by rapper Tyga after she claimed he slid into her DMs.
After being tagged by numerous Love Island fans, Tyga tweeted three cry laughing emojis when he was mentioned in the show.
He also liked tweets that poked fun at Eve's confession, suggesting it isn't true.
