The Emmerdale star, 35, has now left the Channel 5 reality series.
A representative for Pallett told Express.co.uk: "Roxanne decided to leave the CBB house late last night after deliberating for two days with some sensitive issues she felt strongly about.
"She has now been reunited with her fiancé and family and thanks everyone for their support during her time in the show."
A spokesperson for Celebrity Big Brother told Express.co.uk: “Roxanne has decided to leave the BB House. The remaining housemates have been informed.”
Palette’s exit comes after she claimed that she was punched by fellow housemate and ex-Coronation Street actor Ryan Thomas during a play fight.
The actress initially appeared to take the incident as a joke as she playfully referred to Thomas as a “woman beater”.
She told him: “That b***y hurt”, leading the star to reply: “Did it? Sorry.”
Pallett went to the Diary Room afterwards where she said: “Big Brother, can I talk to a producer, please? I want to talk to a member of the production team.
“He punched me like a boxer would punch a bag.
