She shot to fame after being arrested in 1995 for supplying prostitutes to high profile celebrity clients and she served 21 months in prison.

After losing her fortune and selling the rights to her story to US TV channels and to Paramount Pictures, Ms Fleiss ran a launderette in Nevada.
She will appear in the Channel 4 show with footballer and actor Vinnie Jones, signer Dane Bowers and rapper Lady Sovereign.
Across the Atlantic, Sharon Osbourne has been announced as a participant in this year's US Celebrity Apprentice.
