New BB ad keeps fans guessing

Channel 4's latest BB advert has finally given viewers a glimpse inside the house - but has posed even more questions with the introduction of a new tagline.

The new commercial - which began airing yesterday (Friday) - features brief shots of the interior, all partially obscured by the BB logo.

The ad reveals:

• grass green sofas
• yellow walls around the diary room area
• an outside spa
• blue walls in the garden

More insightfully, BB announcer Marcus Bentley signs off the advert with the tagline: "What happens next? You decide."

The tease has led to some speculation that one contestant will be a mole, with a remit to act under the viewers' orders.
