Or so it appears.
These days, Miley is more likely to be seen making "good girl" choices in everything from her men and music to her next travel stop...
So what gives, M?!
Yesterday, the teen queen announced she will be joining the Starkey Hearing Foundation for a return visit to Haiti, where she will be bringing—get this—the gift of hearing!
Saint Cyrus? The newer, younger Angelina Jolie?
"After I went on my first mission to Haiti with the Starkey Hearing Foundation, I felt so drawn to helping others hear for the first time and immediately wanted to look for another chance to go back and help again," Miley explained in her speech at the Starkey Hearing Foundation's So the World May Hear Awards Gala in Minneapolis on Wednesday.
And check out this, dare we say adorable, video that smiley Miley did for the charity crew while in Haiti.
"I grew up around music with my brothers and sisters and couldn't imagine what it would be like if we couldn't hear the magic of music," Cyrus continued. "It's had such an influence on my life—so I want everyone to have the ability to enjoy sound as it was intended."
And who's one musician in particular that has influenced M.C.?
Ms. C was spotted at the singer's concert Friday at the Hollywood Bowl, where Dolly sang a Hannah Montana song and gave a public shout-out saying her goddaughter Miley was in the audience!
Cyrus had even emailed Dolly ahead of time to say she was going to be at the show!
A Miley Cyrus who anticipates and spends her Friday nights watching sixty-something country singers? A bit of a reformation for the notoriously party-lovin'gal, for sure.
And after a hiccup in their relaysh, Miley and her Last Song BF, Liam Hemsworth, have been going strong and staying super under the radar. Très uncharacteristic for the teen idol who has seriously flaunted her BFs in the past!
But we think it's totally smart of Miley to stay with her man, as he is about to blow up for his role as Gale in The Hunger Games.
We're sure that Miss Hanna Montana wouldn't mind being on the arm of an A-list actor!
And in order to keep her man, seems like Miley has had to mature a bit. Gotta say, we're proud of you, babe.
Or is this merely temporary for the gal who can't be tamed?
