Hottie Miley Cyrus and her older bro Trace not only share good genes and a love of music, but if Trace has his way, they’ll also share matching tattoos! The Metro Station rocker says he hopes to get a matching tattoo with his sibs, including lil’ sis Miley — that is, of course, once the 16-year-old turns legal. “I already have a matching one with my dad, there’s no reason I wouldn’t do it with my siblings,” he tells OK!. “Someone you’re that close to, it’s something that means something to you obviously, so why wouldn’t you do it?” he adds.

The 20 year-old, who got his first tattoo at 18 with his mom by his side and is now completely covered in ink, has been touring with Miley since September. Although he’ll have to wait two years before he can share matching tats with his sis, there is one thing they do share on the road — relationship advice.

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

Before the tour wraps and Trace starts working on a new album with his bandmates, there is one more thing to look forward to — mom and

son tattooing in the back of their tour bus.

“My mom’s going to get a ribcage tattoo that is definitely the biggest tattoo she’s ever gotten,” he says. “I’m definitely proud of her for that. It will definitely be a little bit different of an experience for me. I’ve never gone to get a tattoo with my mom ever. She’s taken me to get a tattoo but we’ve never both gotten one at the same time.”
