A Loose Woman, "The Queen of Porn" and two sex tape stars are among the somewhat dubious line-up for the latest series of Celebrity Big Brother.

Loose Women panellist Sherrie Hewson, porn star Jenna Jameson and US TV stars Tila Tequila and Farrah Abraham are among the housemates in the new UK vs USA themed series of the Channel 5 reality show.

TV presenter Gail Porter, The Bill star Chris Ellison and reformed Hollywood bad boy Daniel Baldwin also entered the house tonight, along with Atomic Kitten Natasha Hamilton, X Factor rejects Chloe Jasmine and Stevi Ritchie and former Apprentice contestant James Hill.

Some of the US contestants may not ring many bells with viewers, with The A-List: New York star Austin Armacost and hip hop artist Fatman Scoop completing the line-up.

Jameson, 41, has been dubbed The Queen of Porn having been in the business since she was 18 and holding over 35 adult-video awards to her name.

She said: "I guess people think that I'm going to be like, 'Orgy!'

"I'm on the straight and narrow and I always have been but I'm in a business and porn just happens to be my business. But I'm not here for porn, not yet."

Ex-Coronation Street star Hewson, 64, follows in the footsteps of her former co-star Ken Morley who had a controversial stint in the house during the last series earlier this year.

Hewson, 64, revealed: "I haven't talked to him about it but I advised him that it probably wouldn't be his thing. I think it is a difficult thing to do."

Scottish TV presenter Porter, 44, is best known for having her naked picture projected onto the Houses of Parliament in 1999, but has since publicly battled alopecia and depression.

Ellison, 68, starred as bent copper DCI Frank Burnside in ITV police drama The Bill from 1984 to 2000, while Baldwin, one of the Baldwin acting dynasty, is perhaps best known for his many run-ins with the law. His brother Stephen took part in Celebrity Big Brother UK in 2010.

Mother-of-four Hamilton rose to fame with the girl group Atomic Kitten, while Tequila and Teen Mom star Abraham are perhaps more famous for their sex tapes now than their reality shows.

Bookmakers William Hill are already tipping Gail Porter as the favourite to win the show, with odds of 8/1. Fatman Scoop is the rank outsider at 33/1.

A William Hill spokesman said: "Gail Porter is an obvious choice and we cannot see any of the American contestants lasting very long!"
