From Sylvester's Stallone's mum to Jermaine Jackson and former MP George Galloway – there have been some surprising housemates on Celebrity Big Brother in the past.
But there is one unexpected star who says she is desperate to go on the reality show, Britain's own Joanna Lumley.
The striking 63-year-old Absolutely Fabulous actress – known for her support of the Gurkhas – revealed a passion for the programme while attending this week's National Television Awards.
Joanna told the Telegraph she had been "beating at the doors" of the CBB house to be allowed in, particularly after the appearance of former Dynasty star Stephanie Beacham this year.
"Maybe the time will come and they will weaken," she said.
"They will get on to the Z list and I will be there."
If the slender blonde does want to make her mark, she will have to hurry.
The current series, starring Vinnie Jones, Stephanie, Ivana Trump and musician Dane Bowers, is the last.
