Harry Styles has been allegedly acting like a "stranger" towards other 1D members, reports the Independent Woman.

According to the report, Harry has been acting aloof - from almost missing the Global Success Award acceptance at this year's Brit Awards to allegedly having another life in the US due to Kendall Jenner.

The 1D member got on stage late for One Direction's Global Success Award but defended that he had to go to the toilet. The problem is, other 1D members think otherwise, reveals an unnamed insider to The Daily Star.

Citing the British newspaper's insider, the Independent Woman reports, "There were a couple of the lads who thought Harry did it on purpose just to get all the attention."

"It's as if Harry isn't part of the group. It's going to come to a head now because for the first time in months they are going to be spending every day together as they rehearse for this summer's tour."

The insider also spilled that the 1D member seems to be leading two lives, especially since he reportedly frequents the US where alleged love interest, Kendall Jenner, is based, notes the Independent Woman.

"It's like he has two separate lives now. One in America and his work with the band. Now he's going to come back in and act like they are all best mates again? It's unlikely!" The Daily Star's insider said.

Whether Harry Styles is distancing himself from Zayn Malik, Louis Tomlinson, Liam Payne and Niall Horan or simply having some "me time," the rest of the band members are reportedly anxious about his behavior, says the Independent Woman.

"The boys want reassurances from Harry that he's in the group for the long haul. They won't let him just use them for his own career ambitions. They want to know what's really going on," the insider added.

The boys will kick-start their Where We Are world tour this summer.
