Liam Hemsworth has cancelled an upcoming appearance at the world premiere of his new movie following his split from Miley Cyrus.

The 23-year-old Australian actor - who is currently laying low in Sydney - was set to appear at a red carpet screening for his new film 'Empire State' at the Gasparilla International Film Festival in Tampa, Florida on Tuesday, March 19, but has pulled out in favour of staying close to his family.

A source told E! News that 'The Hunger Games' star had been scheduled to attend the event with his co-stars Emma Roberts and Dwayne 'The Rock' Johnson.

Liam has been spending time with his brother Chris Hemsworth, his wife Elsa Pataky and their nine-month-old daughter India Rose and he has been enjoying some down time with his loved ones, as his contemplates his future with his 20-year-old fiance.

A source previously said: ''He doesn't seem especially sad [or] happy. He seems to be enjoying seeing his family as far as we can tell.''

Miley has stayed in Los Angeles to deal with the fallout from their break up.

Although they are not a couple at present, the former 'Hannah Montana' star wants to get back with Liam once he learns not to be so controlling.

A source said: ''Miley is a fiery character, and they do fight, but she is crazy about Liam. She isn't ready to accept it might be over for good.''

Another insider added: ''If Miley has her way, the break-up won't last because she's head over heels for Liam and ultimately doesn't want to lose him.''
