Photos of Miley wearing a bikini at a Miami hotel at the weekend reveal that the teen star has gone and got herself her very first tatt.
Impressively though, it's not the name of a boyfriend, a dolphin, or a line from Twilight... instead, Miley's tattoo reads "Just Breathe" in honour of her friend who died three years ago from Cystic Fibrosis.
"Just Breathe" is the slogan for the Cystic Fibrosis Foundation.
That's actually quite a nice tattoo considering what she could have gone with. Check out some people with a bit less tatt-taste than Miley in our Worst Ever Tattoos gallery...
