Although ironically the boy band star is not actually legally old enough to drink alcohol yet.
The pair first sparked speculation of a romance back in October, when they shared a drunken kiss at a party and were caught on camera flirting during the reality series spin-off show broadcast on ITV2.
Floppy-haired Harry was later quizzed about the kiss, which can be seen in the video below, but he fails deny the accusation while quipping that Caroline is 'hot'.
Last month, the pair were seen sharing desserts at a restaurant in St Martin's Lane Hotel, London, before leaving together in the same taxi.

'Caroline is a worldly woman, who is never short of male attention. Anne just feels Harry needs to stick to girls his own age and says Caroline should back off!'
After much speculation of are they or aren't they, Caroline broke her silence on toyboy Styles in an interview with Now - but still failed to cement whether they are an item.
The 32-year-old presenter previously received death threats on Twitter from diehard One Direction fans, warning her to steer clear of their idol.
But Flack maintains she has done nothing wrong and that people simply 'aren't accepting of big age gaps'.
Caroline said: 'I feel like I shouldn’t have to worry about what I do. But it’s a social thing that people aren’t accepting of big age gaps.'
Defending the 15 year age gap between them, she added: 'I keep thinking, "What have I done wrong?" But I haven’t done anything wrong.
'What’s hard for me to get my head around is people saying it’s disgusting. I don’t think it is.'
But Harry has stood by her and been very supportive: 'He told me: "Don’t listen to Twitter.’ He became the mature one at that point. I was like: "I know but it’s still quite hurtful." I try not to say anything back.'
