Sophie's ego has been wounded after Big Brother gave her magazines speculating that she may be pregnant because of the weight she has gained on the show.
The 20-year-old was also angry at Kris's refusal to deny rumours that he could have impregnated her in the house.
She said: "People think I'm a big fat pregnant woman and girls will think I'm a slag!"
Rodrigo replied that people would not think she is fat, but might consider her "chubby".
"They make me feel pregnant," Sophie added. "I know how Britney Spears feels. I'm going to shave my head!"
As Rodrigo continued to tease her, the model insisted that she had not had sex with Kris in the house.
