Sam will now be up for the public vote alongside Liz Jones and Jim Davidson, meaning one will leave the house in Wednesday's show.
When Big Brother made the announcement of who faces the boot, the housemates gasped when Sam's name was read out.
BB then played a recording to the house of Jim and Liz nominating Sam. Jim said: "If she vanished for two days, you wouldn't know she was gone."
He continued: "She never starts off any conversation with me and never tries to befriend me and so I'd prefer to spend my time with the others rather than Sam."
Liz said: "Even though I've been really nice to her, she hasn't really made an effort to talk to me."
Some of the housemates later discussed how they felt Jim had voted tactically, as "he knows Sam is favourite to win".
Linda Nolan said: "I think he wants to win. You can't guarantee she will be fine. None of us thought Lionel was going to go. What if people don't pick up the phone for Sam and they voted tactically?"
Luisa Zissman also claimed that Jim had said to Sam: "You know I did that because you're going nowhere."
Jim tried to appease the disgruntled housemates by claiming that the "mathematics doesn't work out". He added: "I had to change my nominations because they wouldn't believe me..."
