Tamera Foster and Sam Callahan(01 of08)
Open Image ModalIn a year that saw Sam Bailey and Nicholas McDonald competing in the live final, it was Tamera Foster and Sam Callahan's relationship that had people talking outside of the show.
It was reported the couple split a year later, so she could focus on her career, after being signed to Simon Cowell's label.

Chloe Jasmine and Stevi Ritchie(02 of08)
Open Image ModalWhen Chloe and Stevi were first rumoured to have got together while they were still on 'The X Factor', we assumed it was completely fabricated... but it turns out they really were an item.
After a turbulent start, the two later got engaged, and entered the 'Celebrity Big Brother' house together in summer 2015.
However, they split a year later. (credit:Stuart C. Wilson via Getty Images)

Zayn Malik and Perrie Edwards(05 of08)
Open Image ModalThat's not the end of Zayn's 'X Factor' love story, though. Once he'd split from Rebecca, 1D appeared as musical guests on the ITV show, the same series that Little Mix were competing.
Zayn immediately took a shine to singer Perrie Edwards, and it wasn't long before they were rumoured to be dating, and later announced their engagement.
In summer 2015, though, it was reported they'd gone their separate ways, with Perrie now linked to Luke Pasqualino and Zayn constantly photographed with new girlfriend Gigi Hadid. (credit:BerettaSimsREXShutterstock)
