10. Jenna Jameson
Not many pornstars are famous enough to be called genuine celebrities, but Jenna Jameson is certainly one who is. Now that her adult career is over and given that she has led quite an interesting life - what with her business ventures and long-term relationship with UFC star Tito Ortiz (and other brief relationships with celebrities such as Tommy Lee and Marilyn Manson) - she'd make a very intriguing housemate. The UK's Celebrity Big Brother series always tends to have one or two American stars and Jameson could be the next one to make the trip over the Atlantic. Her various other appearances on TV shows and in movies such as Family Guy, ECW Wrestling, Howard Stern's Private Parts and Zombie Strippers mean that she is known to quite a large global audience and I'm sure she'd be a very big draw - and a realistic prospect for Channel 5 to consider.
