A source told Heat magazine (via EntertainmentWise): "They do everything together. They're very close and their friends overlap. Harry's not got a lot of people he can trust and the lines could easily blur," adding: "Everyone that knows them has speculated that Harry's in love with Lou, but he's as confused about his feelings as anyone."
The insider noted: "Lou's been there since the beginning - she and her pals have become some of the most important people in his life. He used to idolize her and Lou and Tom were the ones who changed his style and made him become a bit more hipster," the source explained.
