Celebrity Big Brother housemate Vinnie Jones managed to scare a cameraman in the BB house today.

Vinnie crept up on the staff member in the dark and banged on the mirror.

He laughed: “He was a big fella but he looked like he sh*t himself!”

Stephen revealed his own theory on the cameras saying:

“I think there’s someone watching all the time but the cameras are not necessarily rolling,” he said.
