is making her fall tour a family affair: The teen pop star announced today that her big brother, Trace, will join her on road with his synth-pop band Metro Station as her opening act.
Starting on Sept. 14, the Cyrus clan will criss-cross their way through North America until December. Just don't expect any sibling rivalry on the tour bus from these two performers, who both have nothing but admiration for one another.
"Having my big brother open for me is a dream come true!!!!" the 16-year-old star said on Twitter today. She then posted on Trace's Twitter site that they're "gonna have the DOPEST TOUR OF ALL HISTORY!!!!!"
"Me and Miley have been so close since I was a kid," Trace, 20, told PEOPLE last year. "Every time I watch her perform it blows me away. She thinks I'm one of the coolest brothers she can have because I have tattoos and I'm in a band but I don't think she realizes that I have like the coolest sister in the world."
