Former child star MILEY CYRUS is embracing her transition into adulthood by posing bra-less in a sexy covershoot for America's Cosmopolitan magazine.

The singer/actress, who is engaged to actor Liam Hemsworth, decided to bare some skin and go without a shirt as she rocked a white blazer and matching low-slung trousers, showing off her cleavage and toned stomach, for the upcoming March (13) edition of the women's publication.

Quoting lyrics from the Black Eyed Peas' track My Humps as she alerted her Twitter.com fans to the new photo, she wrote, "My lovely lady lumps. Check it out."

In the accompanying interview, Cyrus insists she has no regrets about how she's handled her rise to fame, and claims the negative press surrounding the famous leaked images showing the 20 year old smoking from a bong have actually enabled her to move on from her days as a clean-cut Disney star.

She says, "Some of the worst things that have happened in my career, like things getting leaked, have actually been what's best for me, because people knew when I was on (kids' show Hannah Montana) that I was really growing up. I never faked anything."
