We love a good X Factor romance. But why do they always have to involve seedy age-gaps? We had Rebecca and Zayn from One Direction last year, Danyl Johnson and [removes name before arse is sued] a few years before that, and now we've apparently got Harry Styles and Caroline Flack getting it on too. Why can't we just go back to the sweet and innocent times of Diana and Eggnog? We still get choked up about how that one ended.

So, Harry and Caroline - Harroline - is it true?

Rumour is that they were caught locking lips at an X Factor afterparty following the results show last Sunday. And it's that dastardly Dean Piper at the Sunday Mirror who's spreading the rumour, claiming to have had spy there at London's W Hotel watching it all unfold. This is how they saw it:

"You could tell Harry was loving every moment. He was poised ready for quite some time as they were talking, and in the end Caroline didn’t say no.

They had a big passionate snog and it caused mild hysterics with the group of people they were with. They looked really into each other and left in a cab together, eventually going their separate ways – much to the amusement of the group."

Caroline's 31, Harry's 17. He was born in 1994, she was born in 1979. The longer you stare at the numbers, the weirder it gets.

As fishy as it may sound though, there does seem to be a little bit of substance to the rumours. We're no Sherlock Holmes, but their respective tweets from yesterday look slightly suspicious when placed side-by-side...

Make of that what you will.
