Singer and actor Billy Ray Cyrus is a proud father of six, but not all of his children are biologically his. Two of them, Brandi and Trace Cyrus, are adopted — a fact that's long been known but recently sparked renewed interest.

Trace Cyrus shared an emotional plea to his father, Billy Ray Cyrus, following the country singer's performance after Donald Trump's inauguration. Trace, 35, is the son of Tish Cyrus and was adopted by Billy Ray in 1993 after the former couple got married. This makes him the brother of Brandi, Miley, and Noah Cyrus.
