Viewers shocked by feud between these two Love Island: All Stars contestants

The episode concluded with tensions running high

The episode was nearing its end when Maya Jama revealed this season's first bombshell, none other than Scott van-der-Sluis.

When he was asked to call out which couple he believed was "no good," he immediately pointed to Belle and Sean, and added that Sean "isn't even an All Star."

“Watching you on your season, you were one of the worst Islanders ever,” Scott went on, adding he was “up Joey Essex’s ar**.”

Sean was left gobsmacked as he claimed the two had never met before, labelling his words "harsh."

The bitter exchange left fans rather confused, with everyone wondering if they had missed the 'beef' that went on between the two Islanders.

Fans of the show then quickly found a recent tweet, in which Scott shut down the idea of his best mate Whitney coupling up with Sean.

The tweet read: “She’s the only og girl whose post he liked,” attaching a screenshot of Sean liking Whitney’s post.

Scott simply replied, by tweeting "no," to the suggestion of the couple.

Viewers took to social media to express their confusion, attempting to piece together what had happened between the pair.

One viewer wrote: "Genuinely… what did Sean do wrong? Can people educate me on this? I have no idea."

"Why did Scott just start on Sean?" another added.

"Everyone saying Scott coming for Sean is forced must have not seen the way Scott was tweeting about the man during his season," a third explained.
