Niall Horan`s drinking worries father

London: Singer Niall Horan`s father is reportedly worried about his son`s drinking habit. Niall, 18, cannot take care of himself after the booze and his father Bobby Horan is aware of that. "Two beers and he`s falling around," a website has quoted Bobby as saying. Bobby has also asked Niall`s fellow One Direction band member Harry Styles to keep an eye on his son`s drinking habit. "Bobby`s been texting Harry as he is Niall`s closest friend in the band. He knows his son can`t handle his drink and so he has asked Harry to keep an eye on him," a source said. IANS
