Yes, yes we are! So we find out what salacious scandals or other reality TV shows a few of these fame-hungry housemates have been involved in before entering the house below:
Strict Catholic and lingerie model contestant Danielle McMahon has appeared in the colourful pages of men's magazines such as Nuts (RIP) and FHM. She also dished the dirt on ex-BB contestant Dexter and his "designer penis" (no idea) to the Daily Star after they apparently dated for four months last year. Dexter appeared on Big Brother's Bit on the Side last night and denied that they had slept together.
McMahon has her own website with a portfolio of her modelling work and a blog (no-one's going to read that - it's not exactly bubbling over with information or any pictures of boobs).
From a predictable glamour model contestant to an unlikely journalist and war blogger housemate. Northern Ireland-born Christopher Hall is an MA trainee journalist who graduated from City University in London, and contributes to a blog concerning the current crisis in Syria. You can watch him here reporting on the Syrian Solidarity movement.
And back to normality. Former prostitute Helen Wood caused a media furore after she and another prostitute called Jenny Thompson allegedly had a threesome with Wayne Rooney, while the footballer's wife Coleen was pregnant with their first child. The 27-year-old "feisty Northerner" contestant also claims to have slept with a well-known married actor, but he was granted anonymity under a High Court injunction.
Helen's mother Mary, a primary school teacher, and her father Dr Stephen Wood, a music lecturer at Salford University, apologised on behalf of their daughter after the scandal broke, with Stephen lamenting: "I feel desperately sorry about any problems that may have arisen as a result of what she's done. I'm extremely sad if Helen's actions have had wider implications on anyone else."
Kimberly Kisselovich is not just a pretty face and a Playboy Bunny - the glamour model also has a law degree and is trained in martial arts. She's also a keen snowboarder and open-water scuba diver. She cites art, philosophy, health and nutrition as her main interests, and there are loads of completely naked pictures of her on her Twitter page, which we just discovered the hard and humiliating way.
You can also see her do a dance as Playboy's Cybergirl here.
Unsurprisingly Big Brother isn't the first reality TV show that Mark Byron has appeared on. He auditioned for The X Factor in 2011 (doesn't Louis looked utterly delighted when he walks onto the stage), where his vocals were described by Gary Barlow as "truly horrible".
But before even that, the 24-year-old Liverpudlian tried his luck on Channel 4's Shipwrecked back in 2009. "I'm like a mouth on a stick," he declared, and he's not wrong.
You might also recognise Winston Showan, who popped up on ITV2's reality dating show Girlfriends last year (you can see him at around 35 seconds in the above trailer). That lunge was pretty creepy...
And what's this hidden gem we've just stumbled across? Winston's very own 'World Cup Wonder' rap! Classic lyrical highlights include: "Capello is the man, he gets a 10/10. He looks a bit like my dad, he's the crème de la crème. A hundred times better than that idiot Sven... My prediction is Defoe is gonna score a lot, and Crouch's girl is pretty bloody hot." Pure gold.
Pauline Bennett, like Winston, also has a musical background and features as rapper Jazzy P on Kylie Minogue's single 'Shocked' released back in '91. It reached number six in the UK charts and although we have to admit we can't really recall it, it's catchy as hell. Pauline also stars through a keyhole in Minogue's raunchy music video, and went on to perform the hit with the popstar on Top of the Pops... even if it was up on the balcony and away from the main stage.
The 49-year-old contestant revealed that she may have called Minogue's music utter "s**t" to Minogue's face back in the day, so hopefully we'll hear more anecdotes about this in the house.
Steven Goode appeared on The Chrissy B Show - a topical chat show to promote happy and healthy living which airs live on Sky 203 every Monday, Wednesday and Friday - along with 2013 BB contestants Dexter Koh and Charlie Travers. The 23-year-old discussed his relationship with a "very toxic lady", whom he met during a casual night out in a Mayfair casino, only to later discover she was married with two children.
We know it's hardly the point, but he's about to burst right out of that shirt.
Big Brother continues tonight on Channel 5, with a new batch of housemates set to enter.
