Following a surprise text, the boys were sent on a lads holiday to Casa Amor leaving the girls to pack their bags for them.
Millie included her Sagittarius necklace in Liam's suitcase in an attempt to keep him loyal while their relationship faced the 'ultimate test.'
This proved unsuccessful as Liam cosied up to new girl Lillie and even shared a passionate kiss with her.

One eagle-eyed fan noticed what looked like Millie's necklace around Lillie's wrist which didn't sit well with fans.
But previous Love Island winner Amber Gill was quick to respond confirming it to be a 'false alarm.'
Viewers expressed disappointment in Liam as his relationship with Millie had became a fan favourite.
One said: "Millie & Liam were supposed to ******* win, this wasn’t supposed to ******* happen!"
Another said: “Whatever decision I make, I respect Millie” REALLY LIAM?! Got a funny way of showing it."
While one irate fan viewer said: "LIAM IS THE BIGGEST SNAKE!! giving his girls necklace to someone he’s known for 3 days?? MAKES ME SICKKKK"
Will Liam and Millie stand the test of Casa Amor?
