The first six housemates to enter the Celebrity Big Brother house are quite a varied bunch, with Christopher Biggins leading the charge.

The affable actor and TV personality was followed by Loose Women star Saira Khan, US entertainer Frankie Grande, ex-EastEnder Ricky Norwood, Mob Wives star Renee Graziano, and Geordie Shore regular Marnie Simpson.

Here’s what you need to know about everyone in the house so far:

The pantomime regular first found fame in sitcoms Porridge, Whatever Happened To The Likely Lads? and Some Mothers Do ‘Ave ‘Em, but is best known to younger audiences for winning I’m A Celebrity in 2007.

The 67-year-old has also featured on other reality shows including Come Dine With Me and MasterChef.

Christopher – fondly known as just Biggins – has appeared in numerous pantomimes as the dame, but has said he feels he is nearing the end of that part of his career.

The 46-year-old rose to fame as the runner-up on the first series of The Apprentice in 2005, and soon became a familiar face on television, presenting shows including The Martin Lewis Money Show, Guess This House and Temper Your Temper.

Earlier this year she hit the headlines after remarking on Loose Women that she had lost all interest in sex and had given husband Steve Hyde permission to sleep with other women.

“I’ve lived life and I’m proud to be a Loose Woman. I think when people hear my name they think loud, gobby, in your face opinion.

“I just can’t help talking the truth, that gets me into serious trouble,” she commented before going into the house.

She told the show’s host Emma Willis just minutes before entering the house that there is “no subject that is taboo for me”.

The older half-brother of pop superstar Ariana Grande, he recently starred on the American version of Big Brother and has a huge social media following.

The 33-year-old is also a musical theatre star.

He said upon entering the house: “I am the consummate entertainer, if there is a camera that millions of people are going to watch, you’ve got me, ready to go, suit up for entertainment.

“Glitter is an outward personification of my inward personality which is literally just shiny and sparkly all the time.”

Ricky Norwood

Ricky is best known as Fatboy from EastEnders.

The actor’s five years on the BBC soap were not without scandal, as he was suspended for two months in 2014 after being caught on video apparently smoking cannabis.

He said: “Fatboy was East London boy, a bit gangster… You’re going to get to know the real me. Being nice is a strength. I am definitely a ladies’ man, I love women, I’m a lover not a fighter.”

He promised he would add a bit of “cheekiness and a bit of a flirt” to the house.

He said: “There have been a couple of negative press stories about myself and you’ll hear the story in the house, but a mistake is only a mistake if you carry on repeating it. I do have a game plan, to be cool, be calm, it’s not that serious, just laugh man.”

Renee, 48, is best known to American audiences for her role in reality show Mob Wives, which follows New Jersey women who are connected to the mob either through family or marriage.

In an expletive-filled introduction she said: “If you don’t know me you f****n should. I hate liars.

“Mob Wives is about the mafia, when you grow up in it, that’s all you know, you know where to hide the money and no matter what you stick by the family. You violate us, we’re coming.

“I have no filter, I say what’s on my mind and I don’t give a f***.”

She starred on the show for six years before quitting, and frequently argued with many of the other women.

In 2013, she was admitted to rehab to deal with addiction problems.

She was previously engaged to The Only Way Is Essex star Ricky Rayment and has recently split up with her Geordie Shore co-star Aaron Chalmers.
