Olivia Attwood has revealed the dramatic recoupling ceremonies on Love Island can go on until 4am.
The former contestant told OK! that these evenings are "intense" given the quiet of the secluded Majorcan villa and are something of an endurance session for the cast and producers.
She said: "We did some recouplings that went on until three or four in the morning.
"We wouldn't know the time but the producers would be telling us we had to go to bed because it was the early hours of the morning.
"They're awful, they're worse in real life. On TV, they fill the silences with music but it is so deadly silent, all you can hear is the crackling of the fire."

Attwood competed on the 2017 series of Love Island and finished in third place, alongside partner Chris Hughes.
The 30-year-old revealed she struggled to write fresh recoupling speeches for the show, particularly given she was coupled up with Hughes for more than four weeks.
"I got stuck a few times and [the producers] don't give you anything to say but you can go over it with them," she said.
"When you've been coupled up with the same person for four or five weeks, you do just run out of things to say."
Attwood also confessed that there's plenty of opportunity for Islanders to "do bits" in secret during the night — although it's much harder in the daytime.
She said: "When you're in the bedroom, there's so many beds and so much noise from the camera run, the gallery, people whispering, you can do stuff under the covers without people knowing."
Brown, who appeared on the same series as Attwood, said couples had sex "genuinely everywhere" during her time in the villa.
The current series of Love Island is still reeling after the latest recoupling, in which Toby Aromolaran chose to partner with new arrival Abigail Rawlings.
This left his previous partner Chloe Burrows single, until PE teacher Hugo Hammond chose to save her at the expense of new Islander Georgia Townend.

The villa is set to be shaken up this week by the imminent introduction of the annual Casa Amor twist, in which the existing boys and girls are separated and must face the temptation of multiple new Islanders.
