Controversial blogger Perez was shown attempting to lick Katie's face in last night's episode, but apparently he did worse but bosses chose not to air it.
According to The Sun, Perez also "thrusted his hips" at former Apprentice star Katie before telling her: "Lick it good, suck this d***, just like you should."
A source told the newspaper that bosses decided to axe the scenes to prevent a backlash. Reveal contacted CBB about the claims, but a spokesman said they had no comment to make.
Last night (29 January), viewers watched Perez chase Katie around the house and into the garden while trying to hug and lick her.
Later, in the Diary Room, Katie told Big Brother: "Perez seems to be intent on either licking me or doing strange things to me, which isn't so great."
But when Big Brother asked if Perez had done anything specifically that she felt "crossed the line", Katie replied: "It's absolutely fine. I have no problem with Perez."
She added: "He's a mere child. He has the mental capacity of a small junior."
Meanwhile, Perez's return to the CBB house following his two-day stint in a secret room has caused major fireworks among other contestants too.
Last night, Nadia Sawalha came to blows with Calum Best, while Keith Chegwin has also lost his temper with Katie Hopkins.
This Friday, Perez faces eviction along with three other housemates.
