Pop star Miley Cyrus is reportedly avoiding dating anyone because she is not over her break- up with Australian actor Liam Hemsworth.

Sources close to the 21-year-old former Disney star claim that Cyrus has now turned into a "commitment-phobe".

"She's surrounded by some of the hottest guys around, but Miley's turned into a total commitment-phobe. It doesn't take long before they get the message and give up," a source told Hollywood Life, according to Entertainmentwise.

Hemsworth and Cyrus met on the set of Nicholas Sparks film The Last Song, in 2009.

In 2012, Hemsworth proposed to Cyrus with a 3.5-carat Neil Lane diamond ring. The couple made their last public appearance together at the premiere of his film Paranoia at the DGA Theater in Los Angeles, before Hemsworth officially announced his split from the Wrecking Ball singer.

Since her split from Hemsworth, Cyrus has been romantically linked to Kellan Lutz and even Jared Leto. However, Cyrus recently kissed Katy Perry on the lips, during her Bangerz Tour show at the Staples Center on 22 February in Los Angeles.

Then, on 27 February, rapper Brooke Candy posted an image on Instagram, of her engaging in an open-mouth lip-lock with Cyrus.

"She'll do something crazy that turns them off or intimidates them, like blatantly making out with a random girl or gay guy in full view of everyone," an insider told the website.
