Miley Cyrus and her brother Trace are set to mark their bodies with matching tattoos.

Rocker Trace revealed he was waiting for the day when his teen actress-sister would turn 18.

“I already have a matching one with my dad, there’’s no reason I wouldn”t do it with my siblings,” Contactmusic quoted him as telling America’’s OK! magazine.

“Someone you”re that close to, it’’s something that means something to you obviously, so why wouldn”t you do it?” he added.

The 20-year-old further spoke of his close bond with the Hannah Montana star, saying he was confident of her decision-making.

He said: “She helps me with my girl problems, I talk to her about boys she’’s talking to. She has a smart head on her shoulders and anything that she decides is going to be the right decision.”
