(CBS) Selena Gomez has some baby news to share - and it has nothing to do with boyfriend Justin Bieber's paternity suit drama.
The actress/singer announced Friday that she is going to be a big sister.
Gomez, 19, posted a photo of her mother, Mandy Dawn Cornett, and stepfather and Brian Teefey on her Instagram account, along with a caption about her soon-to-be-sibling.
"Momma and Brian are finally letting me share the news," she wrote. "My mommys carrying my baby brother or sister :) I'm the happiest girl in the world!"
Cornett and Teefey married in 2006, according to People magazine. This will be their first child.
