Rihanna is proving once again that maternity style can be runway-worthy.

The 37-year-old billionaire mogul stepped out in Los Angeles on Monday, proudly baring her blossoming baby bump while enjoying a family day with her mother, Monica, 56, and her two sons, RZA, three, and Riot, two.

Clad in a fitted graphic-print white top that stopped just above her belly button and wide-leg monochrome trousers, the singer-turned-fashion-icon turned the sidewalk into her own catwalk. She completed the look with her Fenty x Puma Cat Cleat Jelly sandals, flaunting a pristine white pedicure, plus a green snakeskin shoulder bag and layers of gleaming gold jewelry.

Rihanna’s signature jet-black curls tumbled in a half-up, half-down style, while her glowing complexion was highlighted with products from her billion-dollar Fenty Beauty empire.

The family outing was a rare glimpse of Rihanna’s personal life but one notable absence didn’t go unnoticed. A$AP Rocky, her longtime partner and father of her children, was nowhere to be seen. Sources say the rapper has been busy preparing a “huge surprise” for Rihanna, leaving fans speculating about whether he’s planning a grand gesture or something even bigger.

The outing comes just months after Rihanna stunned the Met Gala by revealing her third pregnancy in a series of dazzling looks, from a custom Marc Jacobs suit-inspired gown to chic co-ords and a sultry afterparty ensemble.

And while her maternity wardrobe continues to break boundaries, Rihanna has been open about the emotional side of motherhood. Earlier this year, she admitted to Harper’s Bazaar that she struggles with “mom guilt,” confessing: “Every decision I make revolves around them, but everything that I love robs me from them… it’s given me a lot more self-guilt.”

For now, however, the superstar seems to be embracing her growing family with trademark confidence and style — leaving fans eagerly waiting to see just what A$AP Rocky’s “surprise” will turn out to be.
