Niall Horan may not be as innocent as he seems to be. The baby-faced member of the popular British boy band, One Direction, has a few problems up his sleeve. Drinking appears to be one of them and thankfully Niall has got Styles on his side to keep watch over him.

Demi Lovato's rumoured flame, Niall Horan, may look adorable but the British singer isn't as adorable as he looks once drunk. Horan is a bit of a light weight when it involves drinking. Multiple reports claim that the One Direction cutie has had his band mates, Zayn Malik, Louis Tomlinson, Harry Styles and Liam Payne, chaperone him once the booze gets brought out.

Due to the concern for Niall's wellbeing and his fans as well, Horan's father, Bobby Horan had sought out the help of Niall's One Direction band mate. Bobby Horan had allegedly contacted Harry Styles to look after his son whenever booze was included.

"Two beers and he's falling around," explained Mr Horan. Another source added to The Daily Star stated, "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."

Incidents involving Niall getting lights-out drunk would be Rochelle Wiseman and Marvin Humes wedding, the Olympic 2012 Closing Ceremony and last weekend's V Festival. Onlookers at said events stated that Niall wasn't as sober as his other mates.

"Niall was completely hammered at the wedding of JLS star Marvin Humes and Saturdays girl Rochelle Wiseman last month, and ended up falling about and saying daft things he later regretted," explained the source.

"He wasn't much better after One Direction's performance at the Olympics closing ceremony. But Bobby trusts Harry and wants him to make sure his son drinks responsibly in future," added the source to The Daily Star.

Well, now that Niall has got Harry Styles to watch over him, hopefully the One Direction cutie won't get as hammered up as the last time beer was included. Apart from Harry, Niall has got three other band mates to watch over him to keep the drunken episodes out of the news.
