We've been glued to our screens since Love Island All Stars returned for its third season.

This is, in no small part, thanks to the bucketloads of drama which this season has been serving. From bombshells on bombshells to simmering feuds, so much has been going on.

On last night's episode, not only were we shocked to see Jessy and Tommy brutally dumped from the villa, we were also surprised to see former Islanders return to the villa in an explosive twist.

You might think that having the former Islanders return is a bit soon, given that the finale is on Monday. However, a former All Stars winner has shed new light on what, exactly, is happening behind the scenes.

Speaking to OK! on behalf of Heart Bingo, Casey O'Gorman explained a) that contestants are moved to a different villa and b) there's a two-day break from filming before the live finale.

"We wake up in the morning, pack all of our cases - that's when I split my head open on All Stars. Everyone in the final saw that I had this massive cut on my head," he said.

"Then you go to a completely separate villa because they'd be taking down all of the villa. That whole day you get your haircuts, the girls would be getting their hair done, you'd be getting pedicures, manicures - all that stuff."

The reality star went on to say: "We went straight into the final with no rehearsals. We filmed a scene for the start of the episode with Maya, which plays during the opener of the show. Filming that 30-second clip for the intro took the whole day. The couple of days before the final, there's absolutely no filming for the actual show whatsoever."

So there you have it!
