Lee Ryan and Jasmine Waltz ('Celebrity Big Brother' 2014)(01 of22)
Open Image ModalLee Ryan was embroiled in a love triangle with both Jasmine and glamour model Casey Batchelor during his time in the 'CBB' house, which made him pretty unpopular with the British public. He and Jasmine went on holiday to Thailand once their time in the house was through, but it ultimately wasn't to be, and she's since branded him a "damaged soul with no money or career".

Steven And Kimberly ('BB15')(03 of22)
Open Image ModalWe'll never forget their romps in the 'BB' house (no matter how hard we've tried...), and Kimberly and Steven even kept their romance going in the outside world, tying the knot in 2015.Sadly, it wasn't to last though, with reports suggesting months later that they had called it a day.
Helen and Paul ('BB2')(04 of22)
Open Image ModalThe original 'BB' love story, Helen and Paul flirted throughout their time in the house but never acted on it because of her boyfriend in the outside world, Big G. However, once they were evicted they stayed together for a number of years. (credit:Yui Mok/PA Archive)

Open Image ModalThough they kept it low-key inside the house, Mikey and Grace were one of the few couples to last in the outside world, and are still married to this day. (credit:Chris Jackson via Getty Images)
Stephanie Davis and Jeremy McConnell ('CBB17')(06 of22)
Open Image ModalArguably the most tumultuous reality TV relationship since Katrina Amy Alexandra Alexis Infield clapped eyes on Peter James Andrea in the 'I'm A Celeb' jungle. (credit:Steve Meddle/ITV/REX/Shutterstock)
Pete and Nikki ('BB7')(07 of22)
Open Image ModalIt seemed at some point or another every woman in the 'Big Brother' house wanted to sink their claws into Pete, but it was ultimately Nikki Grahame who snagged the energetic raver... for about five minutes, that is, until the magazine deals dried up and she found herself single again.

Chantelle and Preston ('Celebrity Big Brother' 2006)(08 of22)
Open Image ModalChantelle and Preston got swept up in a whirlwind romance while shacked up with Michael Barrymore, George Galloway and Pete Burns, but sadly their story ended in divorce.
Cruelly, fate thrust them together again as they both wound up in the 'Ultimate Big Brother' house. (credit:WENN)
Hughie and Ryan ('BB17')(09 of22)
Open Image ModalThey were an unlikely match, but Hughie and Ryan proved all their detractors wrong, staying together and even getting engaged in the outside world. (credit:Channel 5)
Luisa Zissman and Dappy ('Celebrity Big Brother' 2014)(10 of22)
Open Image ModalLuisa and Dappy claimed to be "in love" despite their blazing rows in the 'CBB' house, though she later revealed it was a purely staged showmance they'd gone through with for money from the inevitable magazine deals that followed. (credit:Supplied by WENN)
Maxwell and Saskia ('BB6')(11 of22)
Open Image ModalMaxwell recently revealed that if he'd never started up with Saskia he'd probably have won the series, rather than disco dancing Geordie hairdresser Anthony Hutton. We're less than convinced. (credit:WENN)
Daley and Hazel ('BB14')(12 of22)
Open Image ModalIt seemed like these two were really on the verge of something wonderful... that is until Daley was removed from the house for threatening Hazel with physical violence during a task. (credit:Supplied by WENN)
Marco and Laura ('BB17')(13 of22)
Open Image ModalTheirs wasn't exactly a romance, but we've included them because their week-long shenanigans got 2016's series of 'Big Brother' to a very raunchy start, with boob-biting, choking and one very quick eviction all taking place in a matter of days. (credit:REX/Shutterstock)
Marnie Simpson and Lewis Bloor ('CBB18')(14 of22)
Open Image ModalThe two reality stars seemed like love's young dream during their time in what was undeniably the raunchiest series of 'Celebrity Big Brother' ever (they even shared a manager - what a coincidence!).
However, things took a downward turn after they were evicted. (credit:Rex/Shutterstock)
Chloe Khan and Stephen Bear ('CBB18')(15 of22)
Open Image ModalThat same series, Chloe and Bear hit the headlines with their saucy antics, culminating in a visit from his girlfriend, to break up with him face to face for humiliating her on TV. (credit:Channel 5)
Kinga and Kemal ('BB6')(16 of22)
Open Image ModalDespite never actually being in the 'BB' house at the same time, Kinga and Kemal surprised us all when they revealed they were in a relationship in the outside world. We don't think it had anything at all to do with publicity. Not. At. All. (credit:Harsha Gopal / WENN)
Jay and Louise ('BB12')(17 of22)
Open Image ModalThis 'BB' pair married not long after their eviction, but less than a year later they'd called time on their relationship as they "didn't get on". Oh dear. (credit:REX)
Chanelle and Ziggy ('BB8')(18 of22)
Open Image ModalEmbarrassingly, Ziggy broke it off with Chanelle on national television using the line "it's not you... it's me". We're cringing still to this very day. (credit:Flashburst/WENN)
Edele Lynch And George Gilbey ('Celebrity Big Brother' 2014)(19 of22)
Open Image ModalNo, we can't quite believe it happened either, but it did. The 'Gogglebox' star and B*Witched singer briefly hooked up during their time in the 'CBB' house, though it was not the stuff of lasting romance. (credit:Channel 5)
Josie and John James ('BB11')(20 of22)
Open Image ModalBristolian "randy mare" Josie and Australian Beckham-lookalike John James spent most of their final weeks in the 'BB' house laying around with their microphones off.
They split once arriving back in the real world, with Josie breaking out of the 'Ultimate Big Brother' house to be with him, though it didn't last, as Josie claims he made too many comments about her weight. (credit:Doug Peters/Doug Peters)
Jamie O'Hara and Bianca Gascoigne ('CBB19')(21 of22)
Open Image ModalJamie and Bianca's growing closeness hit a snag when it emerged that she actually had a boyfriend in the outside world.
Although they vowed to make a go of it, there was another turn of events at the end of the series, when Jamie revealed he wanted to go back to his ex. (credit:Channel 5)
