Harry Styles' Pal Talks Taylor Swift Romance!
Will Sweeney says Hazza 'didn't realise' how big Haylor would be...
During an interview with Heatworld, Sweeney addressed the hype surrounding Haylor's relationship, telling the website: "I think he didn't realise.
"Obviously, he's 18-years old and when you've got two of the most famous people in the world [dating]. I don't think he knew what that was going to be like."
Will continued: "It's doubled his chances of everyone wanting to see him. Everyone wants to see him and everyone wants to see her, so when they're both together, it's going to be insane."
The 1D singer's pal went on to reveal that when Harry does fall for a girl, he makes sure the object of his affections knows how he feels and that sometimes, he can be "full-on."
Sweeney explained: "When he's in a relationship, he's full-on in it. One time I remember we went all the way to Birmingham out of nowhere because he decided he needed to see this girl.
"We got a train on the day to Birmingham, got off the train, had now idea where she was going to be, it was raining really hard and we walked across the whole of Leamington Spa trying to find her.
"Then we somehow managed to find an address and it was great, but it was two or three hours of tracking around Birmingham."
He added: "So he goes to great lengths and he's caring, but he's full on. In any relationship he's going to be full on."
Earlier this week, it was claimed that Taylor had planned a romantic break to Venice for Harry's birthday, with The Sun claiming Styles is "pretty gutted" that they are no longer an item.
