The 25-year-old has now returned – and confessed that living there is like being in prison.
Speaking to the Mirror, Lauren said: “I found the filming the hardest to deal with.
“The camera is there when you wake up, it’s there when you go to sleep. I felt like I could never relax. It’s intense.”
Lauren, who is one of this year’s favourites, this week admitted she once spent time in a psychiatric ward and is still on anti depressants.
Opening up about her dad’s death when she was just 11, and her mum’s battle with schizophrenia, Lauren told OK! magazine: “People are shocked as I’m so bubbly but it’s something I’ll have to deal with for the rest of my life.”
Lauren isn’t the only hopeful to criticise the show this week: Monica Michael, who was voted off on Sunday night, insisted they should be allowed to perform their own music.
Monica revealed to The Sun: “I was like, ‘Can I sing an original? Can I sing an original?’ and having to do a cover was really out of my comfort zone.
“I felt so uncomfortable doing that. Obviously it’s the name of the game and it’s an amazing platform so I just had to go along with it.”
