she became famous for being stupid on a UK version of Big Brother - and then went on to present TV shows etc - she then appeared on celebritity big brother as a 'celebrity' but was accused of being racist after comments she made to and about Shilpa Shetty. I believe there was a foot tickling scene with her in the original big brother she appeared on.
She also came under fire for lack of training and eating a curry the night before attempting to run the London Marathon (which she had to drop out of half way round...)
