Zane had already unveiled that his "body count" was 55, while Eilisha was outed for cheating on her boyfriend the day of her nan's funeral.

But what we found about Dylan had the girls' jaws on the floor and his partner Mimi brand him a "hypocrite".

You can find out what Dylan's shocking secret was by watching the video above.

Mimi shook her head in disapproval as she read out one boy's secret: "This boy would only consider a relationship with someone who has slept with 10 people."

Mimi had her bets on it being Niko's secret but was upset to discover it was her very own partner Dylan.

Dylan did his best to try and justify himself but Mimi wouldn't let him get off that easy.

"So what, you can sleep with heaps of people but women can't? Where is the equality?" she snapped.

It sparked plenty of conversations when everyone got back to the Villa with the girls calling out "double standards".

"These men feel entitled to women who are 'pure and angelic' and it's just not reality," Em scathed.

Xanthe thought it was a "toxic" perspective while Mimi felt she'd been lied to.

"The fact that I'm with somebody that thinks like that, I'm embarrassed," Mimi said.
