Dubliner Samantha Mumba's ex boyfriend, rapper Sisqo, is among the stars being tipped to take the Celebrity Big Brother crown this year.
He made the best entrance of the night, posing with a microphone before jumping down the steps and launching into a performance of his 1999 hit Thong Song.
The singer is in the middle of one of the most controversial reality shows yet, with claims that two of the contestants came to blows before they entered the TV house.
Katie Price's boyfriend Alex Reid denied fighting with her ex Dane Bowers as both men entered the Big Brother house last night.
It was reported that the pair came to blows at the glamour model's New Year's Eve party.
Bowers, a former member of boyband Another Level, had a cut to his face on TV last night but both men denied arguing.
The show's host Davina McCall asked Reid if he had fought with Bowers.
"Categorically no," he replied. "I wasn't even aware there was a fight until afterwards."
His answer left viewers wondering if someone else had fought with Bowers, especially when the singer arrived with a cut above his right eye.
The crowd chanted "fight, fight, fight" when Bowers arrived.
Asked about the reported brawl with Reid, he told McCall: "I'm sorry to disappoint you but we actually get on okay. We get on well. What you read isn't true, I'm afraid, as interesting as it sounds."
Once inside Bowers was asked about the cut and told housemates that he had got it a couple of days ago but did not explain how. Reid greeted Bowers with a smile and a hug when he arrived.
The cage fighter, who's been pictured dressed as a woman in recent months, was booed as he arrived and said: "This is why I'm here, to hopefully change these boos to cheers."
Football hardman turned actor Vinnie Jones is already the bookies' favourite to win with Ladbrokes today offering odds of 5/2 for him.
Jones is the highest paid housemate according to reports claiming he's getting £350,000 (€390,000) for taking part, twice as much as last year's eventual winner Ulrika Jonsson.
