Miley Cyrus is going to be an aunt. Her brother Trace Cyrus and Social Network star Brenda Song are expecting their first child, according to Celebuzz. The couple was quietly dating for several months until they made their relationship public on the red carpet for Nylon's magazine in May.
Brenda Song, like Miley, is a Disney child star. She hit it big when she nabbed a reoccurring role on The Suite Life of Zack and Cody.
Trace Cyrus is known for his band Metro Station - and being Miley's brother, of course!
