Niall Horan: I'm always hungry!

Niall Horan clears out the hotel mini bar's food as soon as he gets there.

The One Direction star and his bandmates Harry Styles, Louis Tomlinson, Zayn Malik and Liam Payne are constantly on tour.

Their Where We Are Tour is currently in its North American leg and Niall, 20, is certainly taking full advantage of the perks.

"Just realised I'm absolutely starving, had some sushi earlier , but it never fills me up! Now I have to wait until breakfast. Sh*t! (sic)," he complained to his followers on Twitter.

When one fan suggested he gets a snack, the singer lamented the fact he'd been too greedy earlier.

"you can't when you've eaten the good [food] from the mini bar in first hour of being in the hotel ahah (sic)," he replied.

Tonight and tomorrow One Direction will perform in Philadelphia at the Lincoln Financial Field. Niall is known for interacting with his fans and let him know how much he appreciates them before hitting the hay ahead of the show.

"Laying in bed ! Can't sleep! thinking about you guys! Watching old 1D videos ! thank you guys! Love you so much (sic)," he tweeted.

However, when one follower implored him to go outside the hotel and meet them he was hesitant.

"I'm going to bed ! I'm sorry! really Am! show day tomorrow (sic)," he posted.

One Direction's tour ends in Miami at the Sun Life Stadium on October 5. However, there's not much time for a breather as 2015 sees the On the Road Again Tour kick off in Sydney, Australia, on February 7.
