Bobbi Kristina Brown with Whitney Houston

Bobbi Kristina Brown with Whitney Houston

Whitney Houston's daughter has pulled out of 'Celebrity Big Brother'.

Channel 5 bosses were hoping to land Bobbi Kristina Brown - the late 'I Will Always Love You' singer's only child with ex-husband Bobby Brown - for the latest series of the reality competition, but it appears she has developed cold feet.

A source told The Sun newspaper: "Bobbi was seen as a major draw and it is a massive blow. They knew there were guaranteed fireworks with her in the house and hoped they'd also get some revelations about Whitney. As far as they were concerned it was a done deal. But she did a massive U-turn and sent the bosses into a panic. They'd already lost [Outkast singer] Big Boi, so this was the last thing they needed."

It's thought producers are struggling to sign up big US names for the new run - which will begin on Thursday (22.08.13) - despite having plenty of money to spend.

The latest names being linked to the show are 'Saved by the Bell' actor Dustin Diamond, who played Screech on the hit 1990s teen show, and 'Return of the Mack' hitmaker, Mark Morrison.

A source added: "The latest two names linked are Mark Morrison and Dustin Diamond. They were reasonably big back in the day, but they have completely dropped off the radar and it's unlikely they will pull in many viewers. But with all their first choices pulling out, bosses need to fill the space somehow."
