Lauren told reporters over the weekend that Luke S in particular was merely looking for a relationship on the show to bolster his chances of making the final.
"On Luke's part it's all fake. He went around the house saying he fancied everyone and Ashleigh just seemed to go for it," said Lauren.
"I think he's watched the show and he knows that couples get to the final. It's safety in numbers and hard to split them up. The honeymoon period is over now, they're starting to argue."
The Criminology and Sociology student was also critical of Caroline Wharram and Becky Hannon, who she claimed were "not very nice people".
"It's hard to believe that Caroline was my age and so horrible, she's got a chip on her shoulder," said Lauren.
