The One Direction heart throb is said to have been getting close to the British model after being introduced by mutual friends, but they are apparently not in an official relationship at the moment.
An insider told The Sun on Sunday newspaper: ''When Harry met Daisy there was a real spark. When they see each other they make sure it's in private at night or with a group of friends.''
It is reported Daisy - whose romance with 'Doctor Who' star Matt Smith recently came to an end - has given the 'Story of My Life' hitmaker one of her favourite rings, and her ex-boyfriend knows about their secret dates.
The source added: ''Matt definitely knows about it because he mixes with a lot of the same people.''
Daisy is said to have gotten close to Harry at Alexa Chung's birthday party earlier this month, and he recently opened up about being able to tell whether girls are genuinely interested in him or just his fame and wealth.
He previously said: ''I think you just know. I think it's one of them things where you know if you meet someone who, you know, likes you just because it's you and not because you have stuff.''
