Baby number two is bumping along in style.

Rihanna stepped out in a trendy striped polo as she joined A$AP Rocky for a lunch and shopping date in Los Angeles yesterday — and while Hailey Bieber wore the same shirt just a few days ago, the "Umbrella" singer gave the style a belly-baring twist of her own.

The Fenty Beauty founder, who is pregnant with her second child, wore the blue, red and white striped Loewe sweater ($990) with a pair of baggy jeans, folding the wool style up to make it into a crop top.

She carried a chic Louis Vuitton box clutch and sported Timberland boots, adding a gold chain necklace and an enormous gold earring in her left ear.

Rihanna, 35, went with a simple stud in her other ear, sporting several statement rings and a gold watch along with the same red manicure she showed off on the Oscars 2023 red carpet.

The "Lift Me Up" singer — who is known for her bold maternity style — shaded her eyes with tortoiseshell sunglasses as she walked down the street with her rapper boyfriend, wearing her hair up in a high ponytail.

A$AP Rocky coordinated with RiRi in loose jeans, sporting a green Bottega Veneta vest ($3,500) over a red flannel shirt and a graphic tee.

Rihanna's striped shirt is clearly a popular style, with Hailey Bieber sporting the same top just three days ago as she was photographed with husband Justin Bieber in Beverly Hills.

The 26-year-old model styled her designer polo with a leather jacket, adding loose jeans, gold hoop earrings and a black Miu Miu mini hobo bag ($2,600) to her casual look.

As for Rihanna, her lunch outing follows a busy week for the "Don't Stop the Music" singer, who made multiple outfit changes for the Oscars on Sunday night, including a leather corseted look, a bra top dripping in crystals for her performance of "Lift Me Up," a custom bump-baring Bottega Veneta crop top and a bedazzled bra and skirt with diamond belly chain for the afterparty.

Whether it's a polo and jeans or a leather evening gown, this star always shines bright like "Diamonds."
