When Trace Cyrus, former lead singer of Metro Station, knocked up Disney star Brenda Song, we all thought the baby would be born out of wedlock. Not anymore!

The two announced on Twitter that they’re getting married. Trace tweeted: “I am very excited to say, last week I asked my girlfriend to marry me and she said YES! We are both very excited to be engaged!”

Aside from being Miley Cyrus’ older brother, Trace, 22, runs a clothing line called From Backsteats to Bedrooms (perhaps that’s how the baby happened?). Brenda, 23, will soon be seen in the movie Boogie Town. But expect both of them to be laying low before the baby comes out.
