Devastated
Lucie admitted she once cheated on an ex boyfriend during an episode of Love Island last week.
The ex in question Freddie Hare seems to believe she was talking about their relationship.
Lucie made the confession during the challenge called 'Sliding Into The DM's'.
The game involved the islanders guessing which DM belonged to which islander.
Michael slid into a DM which read, 'I once cheated on a boyfriend whilst on a trip to Australia.'
He guessed it belonged to Lucie and he was right.
Speaking The Sun, Freddie said, 'I’m devastated. Lucie never admitted it to my face, she did it on national TV.'
'I had my suspicions but it was heartbreaking to find out I was right all along.'

Who did Lucie cheat with?
According to reports, Lucie cheated with YouTuber Alex Boulton.
The pair were down under to make a promotional video encouraging people to visit Australia.
However, it seems the adventure turned into much more than just a business trip.

According to Freddie, Lucie told him that Alex had a girlfriend and that there was nothing to worry about.
However, he had his suspicions when she cut off all contact with him upon arriving in Oz.

When Lucie returned home, he refused to collect her from the airport and they soon called it quits.
'She made it all about me not picking her up from the airport, but now I know she was seeing someone else.'
'She was with someone else when I met her. I suppose it’s a bit of a recurring thing.'

Alex confirms the rumours
Alex has since admitted he was the one Lucie cheated with while she was in a relationship with Freddie.
He told The Sun, 'We spent a month together in the same house in Australia.'
'I’m sure you can imagine what we got up to even if it’s not Love Island.'

Charlie Frederick
Lucie had a brief fling with former Love Island contestant Charlie Frederick.
He told MailOnline that Lucie's, 'Most definitely not looking for love! She's only 21! I hope she's going in there with the right intentions.'
'She'll get a couple of Instagram followers on the way, if you know what I mean. She said it herself.'

'I don't even need to say she used my name to get famous. You've got to do what you've got to do to get the Z-list fame.'
He admitted that when he found out she would be entering the villa this year, he sent his mother and sister a text to say, 'How early did I call this? I'm pretty good at sussing people out.'

Their romance didn't last long
Charlie and Lucie met shortly after he left the Love Island villa last Summer.
A week later, they went to Portugal together for a sun holiday.
Charlie recalls, 'It all went really fast... It was a bit of a holiday romance. If you ask me, it was really good, her family were great but it didn't work out. She was too young.'

'We were never in love with each other. I was the one who called it all off.'
'I don’t think we were on the same page. She was a bit immature. She wasn’t really for me.'
'We really didn’t know each other that well, we were just figuring each other out.'
