Here we were thinking it was all just a bit of speculation, but it looks like Liam Hemsworth and Miley Cyrus really are on a break now that Liam has cancelled an upcoming appearance at the world premiere of his new movie, opting to stay down under with his family.

Liam was all set to appear at a red carpet screening for his new film 'Empire State' at the Gasparilla International Film Festival in Tampa, Florida this Tuesday coming, but has pulled out in favour of staying close to his family including big bro 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 fiancé.

Meanwhile Mama and Papa Cyrus are 'desperate' for her to mend her relationship with Liam, with Billy Ray and Tish shocked at the news of the split.

A source told HollywoodLife.com: 'Miley's parents do not want to see this split happen, they're really worried about Miley. They hate the idea of Miley being single, especially now that she's going through such a wild stage. They know Liam's a good influence on her, he's very stable and unlike some guys she's been with they know he's not using her for money or fame. Liam's no angel, he likes to drink and have fun, but mostly he's very focused on his career. He's extremely disciplined and they think he's a good influence on Miley. Without him around to keep her on track who knows how wild she could get, it's a huge worry for them and if she's single they know it will only get worse.'

Miley's parents are also upset that her engagement could be over because of their conservative beliefs.

The insider explained: 'When Miley moved in with Liam before getting married, it was a huge deal. It caused a lot of tension between Billy Ray and Tish because he felt like she was encouraging Miley to go against their faith. Billy Ray got over the fact that they were living in sin when they got engaged -- that was a big relief for him. If the wedding doesn't happen he's going to take it very hard. They have their own issues in their marriage so the last thing they need is another fight over Miley.' Nothing like getting the 'rents involved to help a broken relationship is there. Wouldn't be surprised if Liam just stays in Australia for a while to escape the madness that is the Cyrus clan and their achy breaky hearts.
