Celebrity Big Brother kicked off last night and it’s set to be the steamiest series ever.

After a series of bust-ups and breakdowns earlier this year, it would appear that Channel 5 are planning for a sexier series this time around.

With Geordie Shore and Ex On The Beach stars already making waves in the house, we’re counting down the days until the first pair of celebrities go full-on Laura and Marco.

We’ve got our bets on Marnie Simpson, who’s no stranger to fooling around on national television.

Marnie claimed that she’s up for fun But she’s not shy about stripping off on TV

“I’ve had sex on TV quite a few times,” said the TV star in her introduction video.

The MTV babe claimed that nobody would be off limits for her and revealed that she hopes to get up close and personal with a fellow female housemate.

“I’m not a s**g, but I’m not a nun either. I am bisexual so if there are any girls, I will go there. I’m keeping my options open. I need to get in there and see who’s there.

“I’m definitely after some fun,” she added.

The star’s bedded numerous girls on Ex on the Beach

Then there’s 25-year-old Stephen Bear , who’s probably managed to bed more girls on TV than reality star rival Gaz Beadle.

Despite entering the house to a chorus of boos, the Ex on the Beach hunk claimed that he was planning on using his charm and ladies’ man reputation to win over housemates.

He said: “I’m the winner, I’m not here to come f***ing second place… I’m good looking and I’m eye candy.'”

Former X Factor star and cam babe Chloe Khan is in the business of stripping off her a living – so there’s no doubt she’ll be setting pulses racing in the house.

Within minutes of entering the house, the brunette beauty was already causing a stir when she got hold of a piece of fruit.

“You’re trying to deepthroat that banana!” shrieked Marnie as glamour girl Chloe devoured the phallic fruit.

But don’t forget about Loose Women star Saira Khan , who hit headlines when she revealed she was in an open marriage with her husband after growing tired of bedding him. Although she later apologised publicly to him over her comments.
