The Big Brother housemates have admitted they'll be skeptical of BB after another secret task.
Yesterday saw Big Brother prank Luke S, with the help of the other housemates.
They managed to convince him he had become a star on the outside, and was wanted for TV projects.
He even shot some 'test photos' for a calendar.
"Literally, it was hilarious, do you not find it piss funny?" Becky asked the others after the task. "He was playing with the cameras, I had to walk out, he was doing funny stuff he'd never normally do."
"I've never witnessed anything so funny in my life," replied Caroline.
Scott quipped: "It was so unbelievably bad, I can't wait to see the calendar."
"That was so good for Big Brother… he believed it!" Sara added.
But Becky admitted: "I'm never believing Big Brother."
