Claire, 35, has been named alongside stars including The Hills' Heidi Montag and Spencer Pratt as possibilities for the Channel 5 reality show, which kicks off this evening at 9pm.
And mum-of-two Claire appeared to strengthen the rumours by telling her 100,000 plus followers on Wednesday (2 January): "Right my lovely tweethearts! I wont be able to tweet you for a while."
Hmm... away in the Celebrity Big Brother house or away sunning herself on some island paradise?
As always, the CBB producers are being tight-lipped over who is involved, so we'll have to wait until the latest bunch of celebs make their grand appearances tonight to see who is actually going in.
Another name linked to the show is Hollywood actress Lindsay Lohan, who sparked the rumour by flying into London after Christmas, although she's publicly denied any involvement.
We can still hope though!
