Hailey Baldwin Bieber has her bling on full display while strolling through the streets of West Hollywood with husband Justin Bieber.

On Monday morning, the supermodel, 26, was seen wearing an Alex Moss initial necklace while on a stroll with the singer in West Hollywood, Calif.

The Rhode founder wore the gold “B” initial necklace — a likely tribute to her and her husband’s shared last name — with a white t-shirt underneath a white button-down, and a black tennis skirt.

The “B” necklace was paired with gold teardrop earrings, a pair of black ballet slippers, a black shoulder purse, and a pair of narrow black sunglasses (the latter two both by Saint Laurent).

Justin, 29, sported a brown and white polka dot short sleeve button down, with loose blue jeans, a dark green baseball hat, and a pair of white Nike sneakers with dark green detailing.

Hailey Baldwin Shows Off ‘Bieber’ Necklace and Shares Steamy Smooch with Justin at Hockey Game

Designer Alex Moss tells PEOPLE, “It feels good to know we created one of her favorite and most worn pieces.” Moss continues, “We always aim to create timeless jewelry. The design of the bubble came from a reference directly from Hailey.”

The official account for the jewelry designer shared a close-up video of the necklace on Instagram in late September.

“Iconic Bubble Set Made For @haileybieber ❄️,” read the caption.

Hailey’s recent appearance in the embellished “B” necklace comes after she showcased the necklace in late August and early September.

Fans first got a look at the piece when the model wore the Alex Moss design to the launch of Rhode’s Strawberry Glaze flavor of its Peptide Lip Treatment  (a donut-inspired collaboration with Krispy Kreme) on Aug 28.

During the launch of the skin line’s latest lip product, Justin joined his wife at Krispy Kreme’s Times Square store in New York City. The model wore an all-red ensemble, including a strapless minidress, open-toe heels, and an elegant handbag. The “Sorry” singer, on the other hand, opted for a casual look, wearing a gray sweatsuit, a light pink trucker cap, and yellow Crocs.

After their New York City appearance, the couple, unknowingly, became the face of what Vogue refers to as the “Overdressed Girlfriend, Underdressed Boyfriend” phenomenon, and would later sport matching looks in the following days.

Following the viral moment, Hailey continued to show off the “B” necklace while she matched with her husband at the US Open on Sept. 4.

The Biebers arrived at the tennis tournament in complementary oversized leather jackets. Deviating from her launch look, Hailey styled her jacket with a white mini-dress with chunky gold hoops and the aforementioned necklace.

As for Justin, he accessorized his leather jacket with a black and white polka-dot cap, a pair of funky, pink LOEWE sunglasses, a white undershirt, light-wash blue jeans, and white New Balance sneakers.
