LOVE Island fans have branded Ciaran 'evil and vile' as he reduced Harriett to tears.
Fans of the ITV2 dating show have branded the scenes the 'most dramatic' moment ever.
As Wednesday's episode came to an end the islanders were gathered around the fire pit for a game of 'Never Have I Ever'.
Ciaran called out Harriett for being 'two-faced' behind his back.
In front of the islanders, he said: "People will make comments and then straight after be all nice to me and say, for instance 'ah you need to be careful with him' but then 'ah you're actually really good Ciaran with her, you treat her so well'."

He added: "Cut the bull**** that's Harriett."
Reacting, the 24-year-old said: "Cool. When you're making comments about other islanders and I'm having a conversation with my friend, I'm going to say that.
"Honestly you're so immature it's actually embarrassing."
As Harriett attempted to embarrass Ciaran, he clapped back, saying: "I haven't been second choice like three times in here, so."
Ronnie intervened telling Ciaran: "She's first choice now though brother."
However, Harriett was reduced to tears by the Welsh hunk's comments and stormed off.
Following the scenes, Love Island fans exploded on social media with their reactions.
One said: "Ciaran relax omg and Jess adding her 2pence, she hates Harriet’s guts most drama we’ve had all season."
A second wrote: "Ciaran is such a nasty person."
"Ciaran and Nicole also need to go, there’s was no need for that comment, he’s vile and Nicole just sitting there and doing absolutely nothing, get off my screen," said a third.

While a fourth posted: "Ciaran called out Harriet. Instead of being humble she laughed at him, called him immature and then she paid the price!"
A fifth commented: "Ciaran is literally so hilarious. Y’all can’t tell me anything. He ate up Harriet today."
Love Island airs the fallout from the dramatic scenes tomorrow night at 9pm on ITV2 and ITVX.
