Justin Bieber Introduces New Baby Sister With Sweet Instagram

Lily Rose
Meet Bay Bieber!

A new Bieber has been born. Justin Bieber's half-sister, Bay Bieber, was born at 8:30 a.m. to Justin's father, Jeremy Bieber, and his wife of six months, Chelsey Bieber. The proud papa confirmed the birth of his first child with Chelsey via an Instagram, seemingly snapped just minutes after she entered the world. "We welcomed a healthy baby 'Bay Bieber' born at 830 am," Jeremy wrote.

This is the second child for Chelsey, who shares 11-year-old daughter Allie with an ex; Jeremy has three children already, including 8-year-old Jaxon, 10-year-old Jazymn, and 24-year-old Justin. The "No Brainer" singer was present for the big day, and took the opportunity to snap a close-up of his just hours-old sister.

"Meet the newest Bieber, my little sister BAY BIEBER," he captioned the Instagram of the sweet-faced newborn wearing a pink-and-blue-striped cap with a bow. We have no doubt Bay will be the best little Belieber (try to say that three times fast)! The photo already has more than a million likes, as well as thousands of supportive comments wishing the three-time big brother and his family congratulations on their latest addition.

Hopefully, Bay will be in attendance at Justin's wedding to Hailey Baldwin, rumored to take place in 2019. The celebrity couple announced their engagement last month, and have set the rumor mill spinning with possible details about their wedding.

Hailey's makeup artist had the best hint to offer as to what the bride will look like on her wedding day, telling Refinery29, "I don't know if it'll be a moment for a big look for her. I think she's going to be no different than any other bride, and just want to feel and look like her best self."

As an big sister of sorts, we're sure Hailey will teach not even day-old Bay how to look and feel like her best self all the time.
