When it comes to birth announcements, Justin Bieber and Hailey Bieber nailed theirs with style.

The Grammy winner was the one who picked out the French manicure that the new mom sported in the couple's Aug. 23 Instagram post celebrating the arrival of their son Jack Blues Bieber, according to the person behind the look.

"Justin has been choosing Hailey’s nail design lately," Hailey's manicurist Zola Ganzorigt told Vogue in an interview published Aug. 25, "and it was his request."

E! News has reached out to the pair's reps for comment and has not heard back.

Hailey's manicure consisted of a "more muted nudish white micro French" style on almond-shaped nails," the Los Angeles-based manicurist added.

Jack is the first child for Justin, 30, and Hailey, 27, who had announced her pregnancy in May by posting images from a maternity photo shoot taken the day of a vow renewal ceremony in Hawaii. It marked the third time the couple has exchanged vows since they initially tied the knot in a New York City courthouse ceremony in September 2018.

The couple's birth announcement was followed by a slew of public well wishes, including from their family.

Justin's dad Jeremy Bieber—whose middle name is Jack—appeared to respond to the birth of his first grandchild Aug. 24 with one word on X, former Twitter: "Papa."

His ex-wife, Justin's mom Pattie Mallette, wrote on her Instagram Stories, "Oh my heart. Welcome baby Jack!! I love you so much! Thank you Lord. What a miracle!"

She also tweeted, "CONGRATULATIONS @justinbieber & Hailey. I LOVE YOU FOREVER BABY JACK!!" Hailey's dad Stephen Baldwin responded, "Amen. Congratulations to you and may God continue to bless our family."

Many celebs also shared their congrats.

"I can’t handle this little foot JACK BLUES" Kylie Jenner commented on the Biebers' birth announcement post, which shows Hailey touching her baby boy's left foot, while the Kylie Cosmetics founder's sister Khloe Kardashian wrote, "Jack blues!!!!!! Congratulations!!!!! I love this tiny foot so so much."
