Hemsworth impatient with Miley Cyrus

Hemsworth is shooting his new film 'Paranoia' in Philadelphia, and wants Cyrus to go back to Los Angeles.

"Miley is driving Liam crazy at the moment. While he's on set in Philadelphia shooting his new film 'Paranoia', she gallivants around town shopping, getting pampered in nail salons and just can't sit still," femalefirst quoted a source as saying.

"Then, when she sees Liam after he's finished filming, she chews his ear off about her adventures and can't wait to tell him what she did that day," added the source.

This doesn't seem to be going too well with the actor.

"With the early starts and late finishes, all Liam wants to do is rest, go through his script so he's ready for his role and order a takeout or go for a quiet dinner," the source added.

"Hemsworth told Cyrus that he's in Philadelphia to work and can't focus with her buzzing around him. He even suggested perhaps it was time for her to go back home," said the source.

Both of them met on the sets of 2009 film 'The Last Song'. He proposed marriage May 31 with a 3.5-carat diamond ring.
