Harry Styles feels 'unfulfilled'

Singer Harry Styles is said to be feeling "unfulfilled" by his "rock 'n' roll lifestyle".

The One Direction star is getting fed up of the lifestyle that he and bandmates Niall Horan, Liam Payne and Louis Tomlinson are being subjected to, reports femalefirst.co.uk.

"It's like he's stuck in the rock 'n' roll lifestyle. It used to be so much fun, but he's beginning to feel unfulfilled. And the exhaustion is starting to show," an insider told Star magazine.

"The pressure and uncertainty are getting too much for Harry. He needs to take care of himself but he just wants to party through everything," he added.

Things haven't been easier for departing member Zayn Malik, who quit earlier this year to have a "normal" life, as he is reportedly "freaking out" over a leaked demo he recorded.

Another insider said: "He doesn't need this. It's freaking him out. He left One Direction to get away from this kind of stress, but now he's getting it from all sides. The last thing he needs is more trouble from the label and his friends fighting."
