MILEY Cyrus can’t wait to be an aunt!

The teen star’s brother, Trace, and his girlfriend Brenda Song — who have been dating for just under a tahun — recently announced they’re expecting their first child together.









And sources say Miley couldn’t be happier.












“Miley is very happy for her brother and Brenda,” an insider told HollyBaby.















It was a pleasant surprise and the whole family is supporting them through this time.










“They approve of the baby because they know how much Brenda and Trace really Cinta each other.”
