Miley's Bro: No One Knows Him, He Knows Nothin'

Yes, this studded, nose-pierced rocker is actually the half-brother of fresh-faced, barebacked Miley Cyrus -- but he definitely doesn't act like it.

While the rest of his family has put Vanity Fair on blast for manipulating poor little Miley, TMZ got Trace Cyrus in DC -- and he couldn't care less.

BTW -- Trace is a guitarist and vocalist in the band Metro Station. Who knew?
