THE mystery behind Love Island's Harry and Emma's split has finally been revealed after their flirty chat in Casa Amor.
There has been some ambiguity around the reason for former exes split, with some fans initially speculating if Harry had "cheated".
But last night, Harry was seen chatting to his ex Emma when she sensationally revealed he brought girls back to her house.
She told him: "The fact of the matter is, you've brought girls into our home, and I wouldn't do that to you, because that was the rules, and you think the rules don't apply to you.
"It's my house, Harry. You think as soon as there's a boundary in place, cross it?
"You think, 'oh yes, let me just f*** this up', like there's just no need for any other woman to be in my house."
During the chat, Emma made a remark about "crossing boundaries", with some initially thinking it was about infidelity.
But viewers are now convinced the pair split up but continued living together while Harry brought girls back to her house - which is what Emma was referring to.
One wrote: "I think post-split they were still living together, and she put up a boundary that whilst he looked for a place a place he wasn’t to bring girls back."
A second said: "They could have been living together after breaking up and he brought someone back too. Or she could have been choosing her words carefully. I have always thought some kind of polyamorous arrangement would suit Harry."
A third commented: "They had broken up but were "still living together (it’s really common, especially if they owned a house together) and he brought girls back to the house."
"Yeah, it sounds like the boundary wasn’t having other partners but rather taking them to the house," this person said.
Watch the moment Harry snogs ex-girlfriend Emma in saucy game leaving Helena furious
Another viewer shared: "I took at as they were living together in her house (he moved in rather than them getting a place together) and he brought a woman home."
While someone else said: "I heard this and assumed he was still in there after the break up and bringing girls there even though she was still involved in the house in someway."
However some viewers have insisted Harry did cheat on Emma.
One wrote: "She said he cheated on the pre villa interview."
A second speculated: "Perhaps she believes he cheated but he denied it, but she broke up with him anyway because the boundary was bringing women to their home, so not requiring her to prove they slept together."
This viewer pointed out: "He told Helena he cheated at the beginning of the relationship but seems like he was cheating more than that."
Last night, during a sizzling game of Raunchy Races, both villas played identical games, with the fastest villa winning a lavish party.
"The oldest boy must snog the oldest girl," was a question read out by the Islanders.
Harry and Emma, both 30, then jumped out of their seats to snog.
Snogging for quite some time, the exes locked lips in a sultry smooch.
After it was revealed to each villa that Harry and Emma were the fasted to snog out of the Casa Amor villa and the main villa, Helena was furious.
"F**k you, Emma," she shouted while flashing a middle finger.
Meg joined in and the two women were chanting "f**k you, Emma" over and over again.
Reacting to the smooch Harry shared with his ex, one person penned on X: "THEY DID NOT JUST HAVE HARRY KISS HIS EX FOR A CHALLENGE."
"PRODUCERS I LIKE WHAT YOU DID THERE GETTING HARRY AND EMMA TO KISS," said a second.
A third penned: "They did that just to make Emma and Harry kiss, ruthless."
