TORONTO — Justin Bieber is welcoming a new addition to his extended family.
The pop star and his dad Jeremy Bieber took to social media with the first images of the singer's baby sister, born on Thursday.
"Meet the newest Bieber, my little sister Bay Bieber," the singer wrote on Instagram.
The baby is the first for Jeremy and his wife Chelsey, who wed earlier this year in Jamaica.
Bieber's dad posted photos on Instagram holding his infant daughter with his wife smiling in the background.
The newborn marks the latest development in a busy year for the Biebers. The 24-year-old pop singer recently announced his engagement to model Hailey Baldwin and has been spending much of the summer in Stratford, Ont., with his family.
