The Steps singer has been rumoured as one of the stars to enter the Big Brother house this year, alongside the likes of Heidi Montag, Spencer Pratt, and Rylan Clark.
Richards has remained coy about her involvement, neither confirming nor denying the reports.
However, she appeared to hint at her involvement on Wednesday, tweeting : "Right my lovely tweethearts! I wont be able to tweet you for a while…. so please follow @UrbanAssociates whilst i'm away… lots of love C."
Later, her husband Reece Richards tweeted from her account: "Hi, it's Reece here (Claire's husband) Just got home from work, she's not here and her suitcases are missing. Anyone got any ideas?!!"
The singer would be following in the footsteps of her bandmate Ian 'H' Watkins, who appeared on the show in 2007.
The new series of Celebrity Big Brother begins tonight (January 3) on Channel 5 at 9pm.
