Three other pop stars are in - Lady Sovereign, Sisqo and DJ Basshunter.
Others housemates include actor Stephen Baldwin, actress Stephanie Beacham and former Hollywood madam Heidi Fleiss.

It was widely reported that the pair came to blows at a New Year's Eve party held by Price.
Reid denied the incident as he entered the house, telling presenter Davina McCall "what you read isn't true".
But his comments appeared to be contradicted when Bowers arrived with a cut above his right eye.
Bowers, a former member of boyband Another Level, told housemates he got the cut a couple of days ago but did not elaborate.
Dire consequences
Minutes after arriving in the house, the celebrities were handed their first task.
It was revealed that a Mini had been parked in the garden and the contestants were invited to see how many of their number could squeeze inside.
The celebrities were warned that anyone who was not inside the car within five minutes would face dire consequences.
But the task was successfully completed with time to spare.

Former Wimbledon footballer Jones is thought to be the highest paid housemate.
A portion of proceeds from viewers' votes this year will be donated to the Comic Relief charity, benefactor of the first Celebrity Big Brother series.
The 44-year-old is being paid £350,000 for taking part, according to the News of the World, which is twice as much as last year's eventual winner Ulrika Jonsson.
And Beacham is a well-known actress whose career has spanned decades. She has enjoyed roles in Dynasty spin-off The Colbys, Bad Girls and a recent stint in Coronation Street.
Meanwhile, Fleiss was arrested in 1993, and later jailed, for running a Hollywood prostitution ring. It was reported to have famous clients, although she has failed to name any.

Bowers, Baldwin and Basshunter - real name Jonas Erik Altberg - are all at 7/1.
Bowers, 30, is best known as a vocalist with boyband Another Level in the late 1990s, while Baldwin is the youngest of the Baldwin brothers. Alec and Daniel, his brothers, are also actors.
And 25-year-old Swedish dance act Basshunter had a hit in 2008 with Now You're Gone.
The seventh series has been given the tagline "hell lies in others", and the Big Brother house has had a suitably gothic makeover.
'Most spectacular yet'
Journalists shown around the compound earlier this week noted cushions emblazoned with diamante skulls, and walls decorated with a flame motif.
The diary room, where contestants speak to the show's producers, has been themed on a fairground, with a large chair modelled on the carriage in a waltzer ride.
A show spokesman said: "The diary room chair has taken on many guises over the different series but this one is the most spectacular yet.
"It is really in keeping with the show's feel that nothing is what it seems."
The celebrity series will be followed in the summer by the 11th, and final, instalment of the main show.
Channel 4's director of television Kevin Lygo announced the decision to scrap the show last August, as the 10th series reached its climax.
The programme had been watched by about two million people, compared with an audience high of eight million in 2002.
