I guess she's not a little girl anymore, but still! It seems like just yesterday Miley Cyrus was the squeaky clean star of Hannah Montana, but now she's an 18-year-old actress slash rock star with ... tattoos and a penchant for smoking cigarettes!?

Yesterday Miley was spotted cruising around the valley with a pal, and the former Disney princess gave us a peek at her new ribcage ink just minutes after stopping by a local tattoo parlor. Though Miley didn't get the ink done yesterday, this is the first time we've gotten a glimpse at it, and we're sure she's going to show it off in a magazine shoot or on the beach this spring, so we can't wait to see it!

Now, about that other thing -- what on EARTH is Miley doing lighting up a cigarette?! She's legally old enough to buy them, but this is not a habit we want out beloved teen queen picking up! Tsk tsk. Hopefully this is just a rebellious phase...
