Liam Hemsworth needs a break from Miley Cyrus.

While the Hunger Games actor's relationship with his 20-year-old fiancee is alleged to be in trouble amid claims about his infidelity, the couple are still together but Hemsworth has decided to fly home to Australia for some space.

A source told People magazine: 'Liam did fly home to Australia so they could have a break. He has been spending time with his brother Chris, with whom he is very close.

'Miley is still upset with Liam. She took her engagement ring off to make him mad.

'But, it doesn't mean that they have split. Miley says they are still together.

'Miley is crazy about Liam, but sometimes doesn't treat him great. She likes things her way and tends to play games. Liam is also a strong person and that's why they often butt heads.'

While Hemsworth, 23, was alleged to have cheated on Cyrus with January Jones, 35, insiders insist the pair have been friends for some time..
