The 12 celebrities going into the Celebrity Big Brother house TONIGHT

CELEBRITY Big Brother is set to return with the most explosive line-up ever as stars including Sam Fox, Marnie Simpson and Stephen Bear are brought together in the house with dramatic results.

The Sun Online can exclusively reveal the Celebrity Big Brother line-up for the first time, confirming the trio will be joined by stars including Danity Kane singer Aubrey O'Day, Anthea Turner's ex-husband Grant Bovey and X Factor reject Katie Waissel.

The list of 13 contestants, which we can can unveil exclusively ahead of the show's launch on Thursday, also includes X Factor rejects Katie Waissel and Chloe Mafia, Towie's Lewis Bloor and Christopher Biggins.

However, as the countdown begins until the show hits our screens, CBB bosses are working overtime to sign some last minute additions to the line-up so there are sure to be some surprises on the big night.

Sam Fox

Producers of CBB have spent years trying to sign iconic glamour model Sam, and now they have finally got their wish after putting a big money offer on the table.

The Sun's Page 3 legend turned down a number of offers before accepting what is believed to be a six-figure deal to enter the house in this series.

Sam, 50, combined modelling with a successful pop career and still performs sold-out shows all across the world.

She has also enjoyed a colourful personal life over the years, coming out as gay in 2003 and confirming she was in a relationship with her longtime manager Myra Stratton.

However, the relationship ended in tragedy when Myra died last year at the age of 60 after a battle with cancer.

Sam has made a handful of TV appearances in recent years, joining ITV's I'm a Celebrity…Get Me Out of Here in 2009, and also featuring on shows such as Come Dine With Me and Celebrity Wifeswap.

Marnie Simpson

Stunning reality star Marnie is set to become the third Geordie Shore cast member to join CBB, following in the footsteps of both Charlotte Crosby and Scotty T, who both won the series.

The brunette beauty, 24, is known for her wild antics on the show which made her name, and fans are expecting her to mix things up in the house this year.

Marnie is hoping to emulate the success of Charlotte and Scotty, and could be tipped as another potential winner.

She is also believed to be single and looking for love after splitting from her on/off boyfriend Aaron Chalmers, so fans will be hoping Marnie may be able to enjoy a summer fling during her time onscreen.

Lewis Bloor

Towie hunk Lewis could be a perfect match for housemate Marnie with his chiselled good looks and impeccable abs.

The good-looking Essex lad is sure to attract the attention of the ladies of the house, and may also bring a much-needed dose of drama.

Lewis, 26, may stir up the other housemates as he is not afraid of the odd argument.

He hit headlines back in 2014 when an episode of Towie showed him embroiled in blazing row with with ex-girlfriend Lauren Pope, 32.

His snide remarks about the age difference between the pair shocked fans of the show, and gave Lewis a reputation as fiery character.

Lewis has also shown himself to be a bit of a ladies' man as he recently confessed to kissing castmates including Kate Wright and Chloe Lewis, who is dating Jake Hall.

We can't wait to see what kind of trouble Lewis will get into during his time in the CBB house.

Stephen Bear

Lewis may have some competition when it comes to drama in the form of Vicky Pattison's ex-boyfriend Stephen.

The Geordie Shore star is believed to be terrified that gobby Stephen, 26, will open up about their tumultuous romance during his stint on TV.

He is known for having an eye for the ladies, and gained a bit of reputation during his stint on the third season of Ex On The Beach.

The hunky TV star kept viewers on the edge of their seats as he fell in and out of love with returning singleton Vicky, and even pursued Megan McKenna during his time on the show.

We're sure Stephen is set to bring fireworks to the house and we can't wait!

Katie Waissel

Fans of X Factor may not be thrilled to see reject Katie back on TV - as she became one of the show's most unpopular contestants following her appearance in 2010.

Katie was accused of being too cocky, and failed to win over the audience with her quirky stage performances and ended up in the bottom four for four weeks in a row.

She was repeatedly saved by the judges, but ended up being given the boot shortly after it emerged that she had already been working as a professional singer.

Katie may be in for a frosty reception when she enters the CBB house, but we can't wait to see whether she manages to win over the British public as she takes a second shot at fame.

Christopher Biggins

Reality TV king Christopher is set to become one of the highest paid housemates ever when he enters the CBB house on Thursday.

He is believed to have been offered a massive £150,000 pay deal to join this season of the show, dwarfing pay cheques of other contestants in the past.

Christopher, 67, has been a regular face on the reality TV circuit in recent years, winning I’m A Celebrity… Get Me Out Of Here! in 2007.

His reality TV CV also includes shows such as Celebrity Come Dine With Me, Channel 4’s Celebrity Five Go To… and Celebrity Masterchef.

Renee Graziano

Fiery Mob Wives star Renee Graziano looks set to become the show's most controversial booking this year after making a name for herself as notoriously touch cookie on the hit US TV show.

She is the sister of Mob Wives creator Jennifer Graziano, and is known for her sharp tongue and outspoken attitude.

We're sure Renee will take no nonsense during her stint on CBB, and we can't wait to see her rule the roost in reality TV land.

Grant Bovey

Anthea Turner’s ex husband Grant has snapped up a reported offer of £100,000 to appear on the show.

The businessman, who was declared bankrupt in 2010, is believed to be relishing the chance to boost his profile and bring home a hefty pay cheque .

He follows in the footsteps of his ex-wife Anthea who appeared on the show 15 years ago.

Her appearance on CBB was during the first incarnation of the show, and she was married to Grant at the time.

Their marriage crumbled in 2013 amid allegations he cheated on the TV star with property heiress Zoe de Mallet Morgan.

Anthea came fourth behind  Jack Dee, Claire Sweeney and Keith Duffy.

Aubrey O'Day

Sexy US singer Aubrey shot to fame in 2004 on MTV reality show Making the Band 3, which was created by Sean 'Diddy' Combs.

She won a place in the Diddy-managed group, which became known as Danity Kane, and went on to score a number one album in the US and tour with acts including Christina Aguilera and the Pussycat Dolls.

However, the group was torn apart by drama following Aubrey's spat with Combs, and she was booted out of the band.

She has since gone on to find success on her own before reunited with Danity Kane in 2013, but they were later rocked by a second split amid further drama involving Aubrey and her bandmates.

She went on to form a new band called Dumblonde with fellow former Danity Kane star Shannon O'Bex.

If her track record is anything to go by, we can't wait to see how Aubrey gets on with the other CBB housemates this year.

Beth Chapman

Dog The Bounty Hunter’s crook-catching wife was due to be flying the flag for America in the house.

However, Beth Chapman, who stars alongside hubby Duane on the cult reality show, will no longer be appearing in the CBB House.
The Sun revealed the reality star will not be joining her fellow contestants after having her placed revoked following the rejection of her visa. 

Helen Lederer

Veteran actress/comedienne Helen, 61, is sure to be a popular choice in the house, as she has admitted producers have been desperate to sign her up for years.

The Absolutely Fabulous star told The Sun: “They did ask me once before but I was doing Calendar Girls [in 2009] and I was quite pleased they wouldn’t let me out.”

Fans may be glad she has finally said yes as Helen could be the comedy antidote to all the drama in the house.

The level-headed star could be one to watch and may even be a potential winner in the making. Watch this space.

Frankie Grande

Ariana Grande's younger -half brother Frankie has already been stepping out from his famous sister's shadow in recent years and has forged a successful career as a Broadway star.

As well as starring in numerous musical shows, he has also come out as a social media star with his own YouTube channel and hugely popular accounts on Twitter and Instagram.

He is known for his dapper fashion sense, and even released a perfume with his stylish sister.

Frankie may be the underdog in the series of CBB, but we are sure he will give one of the most memorable performances of the show.

Chloe Khan

Also known as Chloe Mafia, she is the second X Factor reject to feature in this series of CBB, which is throwing her together with fellow wannabe Katie.
