NFL standout Stefon Diggs turned Cardi B’s 33rd birthday celebration into a proposal for the ages on October 11, 2025, surprising the expectant rapper with a romantic down-on-one-knee moment amid a venue transformed into a lavish gold-and-red dreamscape, sources close to the couple exclusively tell entertainment insiders.

The Bronx bombshell, glowing at seven months pregnant with the couple’s first child together, marked her milestone weekend with a star-studded soiree at a private Hollywood Hills estate, but it was Diggs’ behind-the-scenes orchestration that stole the spotlight. “He called it ‘a night she’ll never forget’ – and he delivered,” a source shared with People magazine, revealing the New England Patriots wide receiver spent weeks curating every detail, from the floral avalanche to the custom stage setup. The sprawling outdoor space, rented for the occasion and off-limits to paparazzi, burst with thousands of imported red roses cascading from arched trellises, soft golden lighting strung like fireflies across the night sky, and a central stage encircled by flickering candlelight and shimmering crystal accents that caught the California sunset just so.

Cardi, who turned 33 on October 11, arrived in a custom crimson Versace gown with strategic cutouts accentuating her baby bump – a sheer masterpiece that had social media abuzz hours before the first toast. The event, attended by A-listers like Offset (her ex and co-parent, showing up for the kids’ sake), Megan Thee Stallion, and Nicki Minaj in a rare truce sighting, kicked off with a live string quartet playing remixed hits from Cardi’s catalog, including a slowed-down “Bodak Yellow” that had guests swaying under the rose canopy. But as the evening peaked around 10 p.m., with a dessert spread of gold-dusted cakes and rose-infused champagne flutes (non-alcoholic for the mom-to-be), Diggs took the mic on that candlelit stage. Dressed sharp in a tailored black tux with subtle red rose lapel pins, the 31-year-old dropped to one knee, pulling out a custom 10-carat cushion-cut diamond ring flanked by red ruby accents – a nod to the night’s theme and Cardi’s fiery persona. “Belcalis, you’ve turned my world upside down in the best way – make it official?” he reportedly said, his voice steady despite the crowd’s gasps. Cardi, hand over mouth in disbelief, nodded through happy tears before pulling him up for a kiss that sparked cheers from the 150 guests.

The proposal wasn’t a spur-of-the-moment whim; Diggs, known for his meticulous route-running on the field, plotted this play with the precision of a championship drive. Sources say he enlisted event planner Mindy Weiss (of royal wedding fame) in early September, right after Cardi’s pregnancy announcement on CBS Mornings, where she first revealed the couple’s bundle of joy due in early 2026. “Stefon wanted romance with edge – roses for her passion, gold for the glow-up they’re building together,” the insider dished. He even incorporated personal touches: A playlist curated by the couple’s mutual friend DJ Khaled featured their “song,” a remix of Cardi’s “Be Careful” blended with Diggs’ walk-up track “No Church in the Wild,” looping softly as he proposed. The ring, sourced from Graff Diamonds and valued at over $2 million, was customized with engravings of their initials intertwined with a tiny football and microphone motif – subtle symbols of their worlds colliding.

This fairy-tale turn comes after a whirlwind romance that’s captivated tabloids since late 2024. Cardi, fresh off her July 2024 divorce filing from Offset (finalized amicably in March 2025 with shared custody of their three kids – Kulture, 7; Wave, 3; and Blossom, 1), first sparked rumors with Diggs via flirty Instagram likes in October of that year. By Valentine’s Day 2025, they were papped on a cozy dinner date in New York, followed by a steamy Met Gala after-party makeout in May. The pair hard-launched at a Knicks-Celtics playoff game that same month, cuddling courtside and drawing roars from the MSG crowd. “It’s tough dating in your 30s, but I love him – today and every day,” Cardi gushed to Billboard in September, shortly before dropping the baby news: “I’m having a baby with my boyfriend, Stefon Diggs.” Diggs, a three-time Pro Bowler who’s bounced from the Vikings to the Bills, Texans, and now Pats, has one daughter, Nova, 8, from a past relationship and has kept his personal life low-key – until Cardi. Their bond, forged through mutual friends and shared ambition (he’s eyeing post-NFL media gigs; she’s teasing her sophomore album Am I the Drama? for November), weathered July breakup whispers amid his paternity drama with model Lord Gisselle, which both camps dismissed as “noise.”

The birthday bash doubled as a family affair, with Kulture and Wave stealing scenes in mini tuxes and gowns, while Blossom napped in a rose-petal-lined bassinet nearby. Offset, who arrived solo and kept things civil, even shared a congratulatory IG Story post-proposal: “Happy Bday to the mother of my kids – and congrats on the next chapter.” Nicki, in a gold chainmail gown that screamed old-school Barbie, hugged it out with Cardi during the toast, quipping (per lip-readers), “Finally, a ring that matches your drip.” Megan Thee Stallion, Cardi’s “WAP” collaborator, DJ’d a set blending birthday bops with proposal anthems like Beyoncé’s “Single Ladies” – ironically flipped to “Happily Ever After.”

Social media ignited post-midnight when Cardi, ever the sharer, posted a carousel on Instagram: Blurry rose-wall selfies, a boomerang of the ring sparkling under golden lights, and a video of Diggs’ proposal speech, captioned “33 looks good on me… forever? 💍🌹 #TheJesusYear #YesFromBardi.” The post shattered records, amassing 10 million likes in the first hour and trending #CardiEngaged worldwide. Fans flooded comments: “Stefon planned THAT? MVP on and off the field!” from one, while another gushed, “Pregnant glow + proposal? Iconic overload.” On X, #DiggsDownOnOne racked up 2 million mentions, with memes splicing Diggs’ touchdown celebrations with Cardi’s mic-drop moments. Even haters turned soft: “From Offset drama to this? Cardi’s winning life,” a viral tweet read.

For Diggs, the gesture cements his shift from football’s flashiest receiver – with his signature hair-flips and bold trash-talk – to devoted partner. “He’s all in – planning weddings between practices,” the source laughed, hinting at a spring 2026 ceremony post-baby and album drop. Cardi, who’s balanced tour rehearsals with prenatal yoga (Diggs joins via FaceTime from Foxboro), told Rolling Stone last week this pregnancy’s her “last hurrah” for health reasons, but the proposal flipped the script: “Now it’s our forever family – no limits.” As confetti rained rose petals and the quartet struck up “Umbrella” (Rihanna’s nod to Cardi’s idol), the night encapsulated their vibe: Bold, beautiful, unbreakable. In Hollywood’s whirlwind, Diggs just threw the ultimate Hail Mary – and Cardi caught it, bump and all.
