The pair have been hidden away in a Big Brother crypt playing scary pranks on their fellow housemates, who believe the duo have been evicted.
The housemates screamed more than three times during the day, which they believe means they have failed the shopping challenge. However, the real task was Jay and Anton's and the secret will be revealed this evening in the crypt.
Tasks that were successful in making the housemates scream included red shower water, a skeleton appearing in a cupboard, dead bodies appearing in the hallway and grabbing housemates' legs, and a dog in a cage with Tashie Jackson's head.
Celebrity Big Brother winner Paddy Doherty will return to the house tonight as part of this week's Paranormal Activity movie premiere celebrations on the show.
