Errr, who hasn't Hazza snogged?
While One Direction's rep was quick to deny Hazza and Cags are dating after the curly-haired one was pictured driving the Made in Chelsea star home, apparently the pair have locked lips in the past.
A source told Heat magazine: "Caggie and Harry have known each other a while, before he got with Caroline last year, and they've even snogged. Caggie has a huge crush on him."
Oh Cags, we hate to be the ones to tell you this, but you're going to have to get in line.
Haggie were spotted partying together at a London club last week - the same night the whole 'sitting-next-to-each-other-in-a-car thing happened - and an insider told Heat that things seemed far from platonic.
"They were very touchy-feely with each other, said the source. "It seemed that they knew each other very well. They were all over each other."
Hmm, we think we'll reserve judgement until Hazza publicly declares his love before we start making 'Haggie' badges or anything like that.
After all, it wouldn't be the first time the 1D love machine has been linked with a female now would it? Sorry, that was the understatement of the year.
