In case you were too busy stuffing your face with Quality Street and partying over the festive season to catch up on your reality TV news, here's a super-quick roundup of what you can expect from the latest series.
What time is it on TV?
It launches tomorrow evening: Thursday, January 3 at 9pm. There's a hefty two-hour launch show from giddy host Brian Dowling, followed by the first episode of spin-off series/human zoo Bit on the Side, presented by the delightful Emma Willis.
Of course, there will be a twist on the opening night and producers are promising a "house from hell" and "nasty twists". Business as usual then.
Who is going to be in the Celebrity Big Brother house?
The rumoured list of housemates is stuffed with more soap stars than the Rovers Return on New Year's Eve. Student icon Toadie from Neighbours (Ryan Moloney), ex-EastEnders cast-off Gillian Taylforth, someone who used to be in Heartbeat (Tricia Penrose) and a chap that was briefly in Corrie (Sam Robertson) are all potentially heading into the compound. Soap duo Bruce Jones and Wendi Peters have also been tagged to take part by some newspapers.
If you don't know your Corrie cobbles from your Albert Square don't worry, Claire from Steps, some models you'll never have heard of, Rylan from X Factor and Frankie Dettori are also apparently taking part. It's like a who's who of people you can expect to see in panto next Christmas.
Meet Lacey Banghard
A celebrity in the very loosest sense of the word, Lacey Banghard is a Page 3 Idol winner, whose claim to fame appears to be having a pair of 26GG breasts that she is happy to share. You may not know her now, but you can expect to have seen every curve, flash of flesh and nipple she owns on the Daily Mail sidebar by the end of the series.
Oh, and by the way, that really is her name apparently.
Lindsay Lohan is going in! No she isn't! Yes she is! No, she probably isn't!
The 'Lindsay Lohan is doing Celebrity Big Brother rumour' will just never die. The troubled Hollywood star and Mean Girls actress is tipped to take part every year - anyone would think the producers deliberately leak her name to stoke up interest. Hmm.
The 2013 Celeb BB Lohan rumours have gone into overdrive in this past week because the jail-friendly star has handily flown into the UK at the right time. However, we suspect this is going the same way as that Charlie Sheen rumour a few years back, so don't get your hopes up.
The crazy world of Spencer Pratt and Heidi Montag
If you've never heard of the double-headed reality TV monster that is Spencer Pratt and Heidi Montag consider yourself very lucky. If you're planning on watching them in the Celebrity Big Brother house, you have our condolences.
The rubber-faced duo, who consist of 88% plastic boobs, 10% shiny teeth and 2% fake tan, found 'fame' in the US on the hit reality series The Hills. The duo are publicity hungry, headline-grabbing specialists who are fond of walking off reality shows, walking back into reality shows, getting married, getting re-married, splitting and getting back together.
Throw in some sex tape scandals, weird born-again Christian mumbo-jumbo, dodgy 9/11 conspiracy theories and a bit of bankruptcy and you'll understand a small slice of what you have to look forward to with this pair of oddballs.
They'll make Rylan look like a University Challenge contestant.
There's an igloo!
Channel 5 cut costs when it came to re-designs of the house and the Diary Room, with minimal changes between series. There is supposedly some sort of high-tech ice hotel/ski-lodge/IKEA closing-down sale theme, but to be honest, it looks pretty similar to every other house there's been on Channel 5.
Except for one thing. There's an igloo at one end of the garden. Which is pretty cool. Cool? Igloo? Geddit?
Celebrity Big Brother launches on Channel 5 on Thursday at 9pm.
