Celebrity Big Brother has returned to screens for the first time since 2007, with 12 brand new famous faces going into the house.

First into the house was Latoya Jackson, sister of Michael, who admitted living in the Big Brother house would “be quite a challenge”. The 52-year-old received a resounding chorus of boos from the crowd as she entered the house – setting the tone for many of the housemates who followed.

Also getting a hostile reaction was former Sugababe Mutya Buena, the second celebrity into the house. “I think the Big Brother experience is going to be a big change,” she admitted, “I think I’ll learn a lot about myself.”

However they were far kinder to Hollywood actor Verne Troyer, aka as Mini-Me in the Austin Powers movies.

Troyer, who stands just 2ft 8in tall, was cheered by the crowd as he entered the house – through a back entrance, rather than the usual staircase.

The trio were followed by outspoken Scottish socialist politician Tommy Sheridan, glamour model Lucy Pinder and former A1 member Ben Adams. Both Lucy and Ben were warmly received by the crowd, as was the next entrant, Shameless actress Tina Malone.

Next into the house was rapper Coolio, best known for the 1995 chart-topper Gangsta’s Paradise.

The 45-year-old, whose real name is Artis Leon Ivey Jr, said he had no expectations of what would happen in the Big Brother house but did have some words of wisdom. “What I’m looking forward to most is being the winner,” he said, “I hate to lose.”

Former Liberty X singer Michelle Heaton followed, along with Terry Christian, best known as the presenter of controversial Channel 4 show The Word.

The line-up was completed by Ulrika Jonsson. “I would consider winning as me leaving reasonably sane and emotionally intact,” she said.

In the first twist of the series, a ‘head of house’ will be chosen later on Friday evening. That housemate will live in luxurious quarters separate from the rest of the house and will be the only person allowed to nominate for the first public vote, while gaining immunity themselves.

The new housemates have also been warned to watch their behaviour, following the controversy that surrounded the 2007 series and the alleged racist bullying of Bollywood actress Shilpa Shetty.

Executive producer Sharon Powers said this year’s series would “explore the world of celebrity”.
