Justin Bieber‘s father Jeremy and his wife Chelsey, who tied the knot in February, have welcomed their first child together: a baby girl.

“We welcomed a healthy baby ‘Bay Bieber’ born at 8:30 a.m.,” Jeremy captioned a Thursday-morning Instagram photo of himself, Chelsey and baby Bay shortly after her birth.

He added on Twitter, “Just welcomed a beautiful baby girl into the world. Bay Bieber #babygirl #biebergirl

Justin also shared a photo of baby Bay on Instagram, writing, “Meet the newest Bieber, my little sister Bay Bieber.”

The new addition is the second child for Chelsey, 30, who is mom to 11-year-old daughter Allie, and the fourth for 43-year-old Jeremy, who is father to Jaxon, 8, Jazmyn, 10, and, of course, the 24-year-old pop star.

Throughout her pregnancy, Chelsey has been updating followers on her growing baby bump.

In addition, the new mom continues to share photos of the couple’s children during family outings — most recently at the beach enjoying some ice cream and at a fast-food counter.
