The singer is so upset by the elimination of her pals Keira Weathers and Seann Miley Moore on Sunday's show that she has packed her bags and left the house she has been sharing with fellow contestants, but remains in the competition.
Kiera told the Liverpool Echo: "She told me she's left the house because she was upset but she's still in the competition - although she's packed her stuff."
Lauren previously revealed she and her fellow finalists have received death threats.
She said: "People can be so mean on Twitter, they forget that we're all just normal people.
"A few of us have even had death threats. And we've had people send pictures of themselves cutting our names into their arms. It's horrible!"
Meanwhile, Keira, who received the lowest number of votes and found herself in the bottom three for the second week in a row, admitted she was upset to leave the show.
She said: "I found it difficult leaving Lauren and the girls. But I'm glad to be home and I'm excited to see what the future holds.
"I've had a ball - I still pinch myself! How many people can say they've been to LA with Rita Ora?"
