Celebrity Big Brother 2014: Tulisa fears what Dappy will reveal in the house!

X Factor 2012 final Tulisa

Former X Factor judge Tulisa is reportedly nervous ahead of the launch of Celebrity Big Brother 2014.

The show kicks off on Channel 5 this Friday night and rumour has it her cousin and former N-Dubz bandmate Dappy is set to enter.

He's said to have signed a six-figure deal to take part, and hinted earlier on in the week that he wouldn't hold back once inside.

The rapper tweeted: “All ur gonna see is Nothing but the Realness!!!!! Had enough of certain groups of the media painting me out 2 be some vile monster!! #Watch”

But the news hasn't pleased Tulisa, who is currently awaiting trial on drugs charges.

"Tulisa is scared Dappy may forget the cameras are rolling," a source told Star magazine this week. "Their pasts are pretty colourful and Tulisa's public image has already taken a pounding.

Other names set for the house are rumoured to include TOWIE's Sam Faiers, comedian Jim Davidson girlfriend of ex-England manager Sven-Göran Eriksson Nancy Dell’Olio and soap star Alan Fletcher.

They're all set to be joined by former heavyweight boxer Evander Holyfield, Blue's Lee Ryan, Made In Chelsea's Ollie Locke and American Z-lister model Jasmine Waltz.

Celeb Big Bro launches this Friday night on Channel 5 from 9PM with host Emma Willis.
