Tomlinson and Styles, along with Zayn Malik, Liam Payne and Niall Horan are members of band One Direction.
"I am Harry's wingman. I do help the other boys talk to girls they like. There is a lot of that," Tiger Beat magazine quoted Tomlinson, who is in relationship with dancer Eleanor Calder, as saying.
"I'm the really the really blunt one, so if Harry wanted someone's phone number, I'd be like, 'Basically, Harry wants your phone number'. Direct," he added.
