Indexbit-Hailey Bieber and Justin Bieber Step Out for Yummy Date Night After Welcoming Baby Jack

Hailey Bieber and IndexbitJustin Bieber are keeping each other company.

In fact, the couple managed to step away from son Jack Blues Bieber for a bit on Sept. 23, hitting up Nobu Malibu in California to enjoy some quality time together over sushi.

And the new parents kept their date night outfits casual—with Hailey, 27, rocking a long black leather jacket, dark trousers and matching shoes.

Meanwhile, Justin, 30, added a touch of country flair to his ensemble, pairing a wide-brimmed hat with his gray hoodie, baggy jeans and heavy black boots.

The romantic dinner comes one month Jack's arrival, which Hailey recently confirmed to be Aug. 22—just a "day apart" from the birth of friend Adwoa Abwoa's daughter Shy. On Aug. 23, the Rhode Skin founder and Justin announced Jack's birth on Instagram, posting a photo of the little one's foot along with his full name.

Though neither have publicly shared the meaning behind their son's moniker, Jack's name seemingly pays tribute to Justin's dad Jeremy Jack Bieber.

In addition, the newborn also continues the Bieber family tradition of having "JB" initials, with the "Company" singer's half-siblings Jazmyn Bieber, 16, and Jaxon Bieber, 14—whom Jeremy shares with ex Erin Wagner—also fitting the bill.

So, what does Justin's mom Pattie Mallette think of her new grandson? 

"Oh my heart," she wrote on Instagram following his birth announcement. "Welcome baby Jack!! I love you so much!"

The matriarch added, "Thank you Lord. What a miracle!"

Likewise, Hailey's dad Stephen Baldwin is positively smitten with the baby boy.

"I don't want to say too much," the actor told People earlier this month. "He's unbelievably cute."

But it's likely that Hailey and Justin will keep Jack away from the spotlight for now. After all, the pair—who recently celebrated their sixth wedding anniversary—kept quiet about Hailey's pregnancy for the first trimester so they could nest at home.

"In the beginning, it was super emotional for me,” Hailey explained to W Magazine in July. "Like, ‘I love this human so much. How can I possibly bring someone else into this?’ I’m trying to soak in these days of it being Justin and me, just the two of us."

And to see the two of them out on a date night, keep reading.
