Harry Styles has lately been spending quite a good amount of time in Los Angeles, looking for a house so that he can live in the states. The latest claims explain why he has been away from his motherland.

The Midnight Memories singer reportedly extended his stay in the U.S. during One Direction's break before kicking off the next tour, which made him to become a stranger to the boyband.

"It's as if Harry isn't part of the group," a source said. "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 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," the source added. "They want to know what's really going on ... 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!"

In addition, after hanging out with Johnny Depp previously, Harry Styles is reportedly planning to spend a little quality time with Leonardo DiCaprio, as the actor may want to work with the "Best Song Ever" singer and to see if Styles would be a good fit for any film roles for his production company.

"Leo's invited Harry over to his house for a long weekend when their schedules allow to talk work and women," a source said. "Bradley Cooper will probably be around too."
