CELEBRITY Big Brother bosses are in crisis after failing to sign up the final big name just hours before the new series starts.

As The Sun Online exclusively revealed this week, producers always keep one massive celebrity name back.

5 Celebrity Big Brother bosses are in crisis as their final big name celebrity has yet to sign their contract - with just hours to go before the next series starts

But there’s a major problem because this person still hasn’t signed their contract.

Insiders told us bosses are now clamouring to get the celeb to sign on the dotted line but it’s not going to be as straightforward as they first though.

One TV insider explained: “Everyone is now in hiding ahead of the show starting tomorrow but there’s an empty hotel room still waiting to have someone check in.

“The bosses have been trying to sign this person up for a while but there have been issues along the way and their contract is still very much blank.

“There are lots of frantic phone calls and emails flying around in the office.

“It’s absolutely chaos there right now and they’re pulling out all the stops to get this person into the house.”

The Sun Online has contacted Channel 5 for comment.

Earlier this week The Sun Online exclusively confirmed the thirteen big name stars who would be locked down in the house from tomorrow night.
