Miley Cyrus is 18, and the triple-threat teen idol is once again showing the world she "can't be tamed."

PEOPLE reports that Miley has gotten her fifth tattoo, which is reportedly "a picture of the dream catcher that hangs over her bed with four feathers to represent her four brothers and sisters."

The starlet has two older siblings (Brandi, 23, and Trace, 21) and two younger ones (Braison, 16, and Noah, 11.) She says that "the dream catcher is to protect them."

The former 'Hannah Montana' star also has a "Just Breathe" tattoo on her ribcage in honor of a friend who died of Cystic Fibrosis, the word "LOVE" inked on the inside of her ear, and both a heart and a small cross on her fingers.

"All of Miley's tattoos have a deep meaning to her," a friend says. "They all represent family and friends close to her."

In December, Miley's father, Billy Ray Cyrus, tweeted that he was "so sad" about his daughter's infamous hallucinogenic trip. The video was shot by one of Miley's friends and shows her taking a hit from a large bong and then immediately feeling the effects of the drug, including mistaking someone for her ex-boyfriend Liam Hemsworth.
