Pictures of the "Hannah Montana" star pulling down her top to expose a lacy bra appeared on the Internet last weekend.
It's the second go-round of risque photos for Cyrus, who has hoisted herself as a "good girl" role model, the Los Angeles Times noted, pointing to scantily clothed photos that appeared on her MySpace page.
"Miley is always saying that she owes so much to her family and the way she was raised," teen magazines Associate Editor Mark Cuenco told the Times.
"I hope that's the worst it gets," he said, adding the legion of 5- to 12-year-old "Hannah Montana" fans probably won't even know about the latest scandal.
"The audience of 'Hannah Montana' and the kids that go to see her movies don't (read tabloids)," he told the Times. "They may not ever know these came out. I don't think they will hurt her."
