Hailey Bieber posts unfiltered selfie 4 weeks after welcoming son Jack Blues with Justin

Hailey Bieber shared an unfiltered mirror selfie four weeks after giving birth to her and her husband Justin Bieber's son, Jack Blues.

The model, 27, posted a close-up photo of her glowing, bare-faced skin while pursing her lips on her Instagram Story Thursday.

"hi," she simply captioned the snap, adding a sparkles emoji.

Hailey rocked a subtle nude lip, peachy blush and a sleek, pulled-back bun. She had an electric blue manicure and accessorized with silver hoop earrings and her signature diamond "B" necklace.

The Rhode Skin founder has kept a low profile since welcoming her first child on Aug. 22 , though she did share a snap of her new diamond-encrusted "mom" ring two weeks after her son's arrival.

Meanwhile, Justin, 30, was spotted attending a church service in Beverly Hills, Calif., solo just days after becoming a dad.

The "Peaches" singer announced on Aug. 23 that the couple had welcomed their son.

"WELCOME HOME ... JACK BLUES BIEBER," he wrote on Instagram alongside a photo of their newborn's foot.

Days later, a source shared that Justin was "already a great dad" and had found his "purpose" as a parent.

"[Justin and Hailey are] both overjoyed," the insider told People, adding, "The baby is such a miracle. He's adorable and doing well. Hailey's doing well, too."

The pair announced Hailey's pregnancy in May after renewing their vows in Hawaii .

The makeup mogul, who was six months along at the time, showed off her baby bump while wearing a white lace Saint Laurent dress and a matching veil.

The duo also celebrated the milestone by upgrading Hailey's engagement ring with a new massive oval-shaped diamond bauble.

Justin proposed to the fashionista with a smaller oval diamond, which she now wears on her pinky finger, in July 2018 — just weeks after they started dating .
