Miley Cyrus is going to be an aunt! The teen queen's older brother, the tattooed, inky haired rocker Trace Cyrus, is expecting his first child with Brenda Song, reports Celebuzz. In case her name does not ring familiar, Song starred in 'The Social Network' aka 'The Facebook Movie.' Congrats to the couple on their upcoming bundle of joy!

Song and Cyrus have been quietly dating for a few months, making their first public appearance together as a couple on the red carpet at a Nylon party held back in May. Both have famous and musical exes in their rear view, as Cyrus was once linked to Demi Lovato, while Song was rumored to have dated Joe Jonas, who is an ex of Lovato. That's proof that Hollywood really is a three-mile zone where everyone is all up in each other's business!

Given the rough year that the Cyrus family endured – dad Billy Ray filed for divorce from mom Tish in 2010 which was followed by interviews about the state of the family and Billy's estrangement from Miley -- perhaps this bun in the oven is just what the doctor ordered to further strengthen this show biz family.
