One Direction might be one of the most famous music groups of today but that doesn't mean the members are allowed to do what they want when they are resting in between shows.

According to reports some One Direction members, in particular Niall Horan and Liam Payne, are experiencing homesickness and "cabin fever" when they are forced to stay inside their hotel rooms to avoid fan frenzy.

"This is what ya call 'cabin fever,' this is what happens when you are in a hotel all day without fresh air ! Hahahahahah Liam has gone mental!" wrote Niall Horan in his Instagram account, along with a video showing his band mate Liam Payne doing laps in hotel rooms.

Horan admitted, in a separate report, that being stuck in a hotel can be quite "frustrating."

"I remember in Peru I got up, went into Louis's room and said, 'Right, what are we doing today?' and he said, 'We should go shopping.'" said Horan.

"Then we looked out of the window. There were 10,000 people on the street outside our hotel." Horan added, according to a report by Express.

In a separate report, Louis Tomlinson says that little epiphanies as simple as "the back of a tour bus" can be their escape.

"The tour bus is a little escape, that little back lounge we sit in. Hotel rooms can often be lonely. It's just an easier way to deal with it all," Tomlinson said.
