He had been 'head over heels' for new girl Natalia, after setting sights on her during his time in Casa Amor. 

But despite romance seeming to blossom between them, it looks like Luke Mabbott and Natalia Zoppa are in for an explosive showdown, as she admits she doesn't feel 'ANY sexual chemistry' for the Justin Bieber lookalike. 

In a spoiler clip for Sunday night's episode, while gathered around the fire pit with the Casa Amor girls, Natalia is asked: 'Have you got the ick?' after confessing her feelings for the heating engineer have changed.

Discussing Luke M, who chose to bring her back to the main villa with him, Natalia says: 'I woke up this morning and I just felt a little bit different.

'He kept coming up to me and trying to talk to me and I felt like I don't really want you to talk to me right now.'

The girls ask, 'have you got the ick?' to which Natalia admits: 'I do like him but I don't feel any sexual chemistry whatsoever. I've been stressing about it all day.'  

In a spoiler clip, which aired at the end of Saturday night's episode, Luke was seen questioning whether Natalia has been genuine with him. 

Luke was talking things through with best pal and Luke T and sharing his doubts over Natalia, when he said: 'I don't know if Casa Amor was forced or what?' 

During Friday's episode, viewers saw Luke M admit that he is still yet to kiss Natalia, after the pair decided to take things slow when it comes to their relationship. 

The boys were left shocked by his revelation, but unfazed, Luke said he would 'wait as long as he needs to' when it comes to getting affectionate with the beauty.   

All six girls that entered Casa Amor set their sights on Luke, with all of them admitting they fancied the Geordie lad. 

He was initially attracted to Molly, but seemed to hit things off with Natalia and didn;t second guess his decision to bring her back into the main villa with him. 

Luke had been coupled up with Jess Gale, but ended things with Jess after realising the twin was more interested in Mike Boateng. 

However, neither Jess or Mike stayed single to make a go of things with one another, she recoupled with new boy Ched and Mike decided to couple up with new girl Priscilla. 

Fans will have to wait and see how their conversation plays out in Sunday night's episode, with Sean Paul making a surprise appearance on the show to perform for the islanders. 

Love Island continues Sunday night at 9pm on ITV.
