Billy Ray legally adopted Trace when he married Trace's mother; he and Miley are half-siblings. I think it's commendable that a man adopts a child not of his lineage for the sake of family and unity. :-)

@Pak31.. This may be a dumb question, but if they have the same mother, why are they both Cyrus'? I agree opposites must attract.

Tonya, not sure if you are serious or not but Trace and Miley have the same mother, different father. He was with the band Metro Station but not anymore. That is really all I know about the guy. In the looks department they are on other ends of the spectrum.

Whoa he looks nasty..brenda is beautiful but put the two together and Wham! What a Trainwreck.

this is the first time i have ever seen a picture of miley cyrus's brother they look nothing alike. What kind of music does he play?
