Miley Cyrus issued a statement exclusively to PEOPLE on Sunday, apologizing for a series of playfully provocative fotos that circulated on the Internet last week, as well as those from a racy, as-yet unreleased Vanity Fair foto shoot in which she appears to be nude.

The singer, 15, tells PEOPLE: "My goal in my música and my actuación is always to make people happy. For Vanity Fair, I was so honored and thrilled to work with Annie [Leibovitz]. I took part in a foto shoot that was supposed to be 'artistic' and now, seeing the photographs and lectura the story, I feel so embarrassed."

A fuente close to the singer tells PEOPLE that Cyrus is clothed but shown por renowned photographer Annie Leibovitz in such a way that that the teen appears to be topless.

In the fotos that circulated on the Internet, Cyrus, her midriff exposed, is shown draped over the lap of her then-boyfriend, her producer's son. In another image, a hint of a green bra is evident. (Those fotos alone prompted criticism from conservative TV commentator Bill O'Reilly, as well as words of support from the Jonas Brothers and a fellow disney star.)

Cyrus goes on to say: "The pictures of me on the Internet were silly, inappropriate shots. I appreciate all the support of my fans, and hope they understand that along the way I am going to make mistakes and I am not perfect. I never intended for any of this to happen and I am truly sorry if I have disappointed anyone.

"Most of all," she says, "I have let myself down. I will learn from my mistakes and trust my support team. My family and my faith will guide me through my life's journey."
