Luke A has confessed that he "feels like s**t" thanks to the 20-year-old Surrey girl, who was one of the housemates that voted for him in this week's face-to-face nominations.
Talking about his isolation in the house, Luke A said: "All my life I've been rejected by society. And the same's happening in here. I'm such a loser.
"It just reminds me of school - of being bullied. I just feel so lonely in here sometimes."
Speaking to Lauren Carre about Caroline, he added: "I know Caroline had it in for me - she makes me feel like s**t.
"I don't know what I've done to her to destroy me inside... I really feel she's a bully.
"Why are they getting away with it? Why are they getting away with being bullies and a**eholes?"
Luke and Lauren are the two housemates facing the public vote this week.
