Miley Cyrus hypes up her upcoming music comeback. The former "Hannah Montana" recently tweeted a picture of her sitting behind a computer in what looked like a recording studio. "Guesssss where iiiii am??? #gooooo," so she enthused.

Just a few hours ago, Miley took to Twitter to express her outrage towards a group of cruel pranksters who urged Justin Bieber's fans to self-harm themselves in a mock protest after pictures of him smoking pot emerged on the Internet.

"#cutforbieber? Cutting is NOT something to joke about," she re-tweeted a message from another Tweep. "There are people who are actually suffering from self-harm, this is so disrespectful."

Miley didn't actually take a hiatus from music, but it's been two years ago since she dropped a new album "Can't Be Tamed". The "LOL" actress then spent the following year touring around the world for a promo tour dubbed "Gypsy Tour".

As a prelude for what's to come, Miley released music videos from her backyard sessions. She covered Dolly Parton's classic "Jolene", Melanie Safka's "Look What They've Done to My Song" and Hope Foye's "Lilac Wine" made famous by Elkie Brooks.

After performing "Lilac Wine" which was Liam Hemsworth's favorite, she was proposed by the Aussie hunk.
