The housemates were gathered on the sofa and informed of the results of the first nominations, with Hamilton receiving four nominations and Heidi and Spencer receiving 10.
The news was met with laughter from the housemates, including the American duo, but Hamilton was upset, telling the others: "I'm going to go and pack now, I've just gone from boiling to freezing cold," before heading into the bedroom.
She then told her housemates that she will be voted out because the British public already think she is "crazy".
Speaking to Big Brother, she said: "It's very, very different for everyone...Heidi and Spencer, to get 10 out of 10 doesn't affect their career. It makes me want to draw back from people."
Later, she said that she had decided to stay but "won't be close to the women in the house", before adding: "I know it's the girls."
Rylan Clark told Heidi and Spencer later: "It wouldn't be so hard [for us] if she didn't take it so personally."
Paula is currently the bookmakers' favourite to be evicted from the house on Wednesday, with odds as short as 8/15 being given by some outlets.
Celebrity Big Brother airs on Channel 5.
