London, Aug 21 - 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," dailystar. co. uk 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)
