The rapper has been linked to the show this month ahead of its live launch on Friday night.
Yesterday, Dappy seemed to suggest he had confirmed his appearance with bosses with a pay cheque of £300,000.
Or just £300, we're not too sure.
He tweeted: “U know me I keep it 3 hundred I just signed a dotted line and got 3 hundred!!!!”
Dappy previously dropped other hints he was set to appear in the series, telling fans: "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"
And he added last night: "Sorry about all this my beautiful loved ones!!!! Certain People just can't handle the fact that 2014 is gonna be such a HUGE year for me!!!"
It was claimed previously by The Sun newspaper that the singer, who topped the charts with his debut solo single, had been 'forced' to take part in the show after being issued with a huge tax bill.
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.
CBB launches this Friday night on Channel 5 from 9PM with host Emma Willis.
