Miley Cyrus

Former Disney star Miley Cyrus is the latest celebrity to take a dig at YouTube sensation Rebecca Black.

"It should be harder to be an artist," Cyrus told Australia's Daily Telegraph in preparation for her tour down under. "You shouldn't just be able to put a song on YouTube and go out on tour."

Rebecca Black's "Friday" goes viral, grabs 7 million views (but for all the wrong reasons)

Black, 13, became an overnight phenomenon after her YouTube video of "Friday" got 7 million hits in just a few days. Two weeks later, it has more than 67 million views, but a combination of harsh criticism (Billboard called the song "straight out of Auto-Tuned hell"), sheer curiosity and schadenfreude may have attributed to that number.

Meanwhile, rapper Patrice Wilson, who wrote "Friday" and appears in the video, has come forward to say that Black is not to blame for the schoolyard lyrics.

"'Tomorrow is Saturday, and Sunday comes afterwards.' I mean, everybody knows that, obviously, but I wanted the song to be simple and kind of sweet," Wilson told the Los Angeles Times. "People talk so much about how silly or stupid the lyrics are, but pop songs, they're meant to be catchy and to tell things in a simple kind of way. I feel bad that Rebecca has been getting so many people criticizing the song. Because it was me that wrote it."
