Miley Cyrus fears getting dumped by boyfriend

Teen sensation Miley Cyrus, who is dating actor Liam Hemsworth, is scared of getting dumped by the Australian.

Cyrus, 17, started dating Hemsworth last year after they met on the set of 'The Last Song' but she fears that her 20-year-old beau will leave US and her, any time, Us magazine reported.

"I don't want to be heartbroken. He could go back to Australia any second. But I'm happy. It's different from anyone else because he really is just an awesome friend too," the 'Hannah Montana' star said.

Although the pair have been dating for a year, Cyrus admits she has a crush on '17 Again' star Zac Efron.

"He's gorgeous, he's hot, I don't go see his movies because I'm like, 'He's such a fantastic actor. He's a great actor, but he's hot," she said.
