This year's Big Brother will see the booze padlocked in a fridge until the housemates get dirty and passionate, The Sun claims today.

Up until now, every series has seen the housemates buy alcohol with their shopping budget, but this year producers will only allow them access to the booze to spice things up.

“We don’t want the shopping arriving with the alcohol, then housemates having a blow-out and being bored for the rest of the week," a show insider said. "If the booze is kept under lock and key, we can control as and when they have access to it."

Producers are also reported to have a a plan up their sleeves to encourage a bit of action: "If things are getting fruity and some of the housemates are getting flirty, Big Brother will call someone into the Diary Room and give them the key to the fridge."
