Justin Bieber Is Brother of the Year, Shares Inspiring Message for Little Sister Bay

Justin Bieber knows how to be a great big brother.

The singer took to Instagram on Friday (May 15) to share an adorable photo with his one-year-old half sister Bay Bieber, both rocking beanies and sleek sweatsuits.

JB topped off the cuteness with an even sweeter caption: “Dear baby sis, you will grow up to be a confident, strong, kind, compassionate powerful woman! Excited to watch you grow into the incredible woman you are DESTINED TO BE!”

Bay is Justin’s dad Jeremy’s first child with Chelsey Rebelo, whom he married in Jamaica in February 2018. Bay was born soon after, in August of that year.
