Diva Clash: Miley Cyrus Disses Justin Bieber and Rebecca Black

Singer Miley Cyrus slammed musical artists who launched to stardom by posting clips to YouTube, as she promoted her first tour in Australia.

"It should be harder to be an artist. You shouldn't just be able to put a song on YouTube and go out on tour," Cyrus said when asked about singers like Justin Bieber and Rebecca Black, who got their start on the video sharing website.

The controversial teen pop star spoke to The Daily Telegraph ahead of her upcoming tour in Australia this June.

No circus tricks, a few costume changes and a set list influenced by shout-outs from the crowd, for a ticket price less than $100, will be the key ingredients of her Gypsy Heart shows.

"I don't lip-sync. I would rather someone say I sang like crap than have people see me lip-sync," she said.

The 18-year-old who catapulted to fame in the Disney TV series "Hannah Montana" most recently made headlines for smoking a herbal substance in a bong.

"I mess up. There you go," Cyrus said. "But if you live your life trying to be perfect, you don't really live your life ever," she continued.

She also said she is looking forward to launching her first tour in the country she most recently visited last year -- with then-boyfriend actor Liam Hemsworth.

"I was only there for a week and I loved it so I'm looking forward to exploring and meeting a lot of people. Australians are a lot like southern people. You love BBQ as much as we do," she added.
