Cardi B and Stefon Diggs’ Relationship Timeline, From Rumors to a Baby Boy and Back Again

Cardi B and Stefon Diggs stopped being a rumor and started becoming a public spectacle in May 2025, when the two were spotted courtside at a New York Knicks game and Cardi was seen on the Jumbotron squeezing the NFL player’s cheeks. By then, the speculation had already been circulating for months. What followed was a relationship that played out in the open, on Instagram, at award-season events, on the field, and eventually in the middle of Cardi’s album rollout.

That kind of visibility is hardly new for Cardi, whose love life has been tracked in public since her Love & Hip-Hop days in 2015. Still, the Diggs chapter marked a sharper turn after her split from Offset, and one that moved quickly from gossip to confirmation to parenthood. By June 2025, the pair had gone Instagram official. By November, Cardi had announced the birth of their baby boy. And by early 2026, the relationship seemed to be wobbling in the way celebrity romances often do when they’re both deeply personal and permanently online.

As the story kept developing in real time, Billboard kept a running timeline of the major beats. Here’s how it unfolded.

Oct. 9, 2024: The first rumors take hold

Cardi was pushed into addressing the speculation herself after fans and gossip accounts began circulating claims that she and Diggs had been seen together. Nothing was confirmed, but the chatter got loud enough to force a response on Instagram Live.

“The internet is insane, all these rumors are so f—king crazy, that’s why I don’t wanna address it cause I feel like this s—t funny,” Cardi said on Instagram Live at the time.

Dec. 18, 2024: Cardi says she’s dating

By December, Cardi was openly saying she was “dating” while her divorce from Offset was still playing out noisily online. Offset, for his part, had already made the situation uglier with since-deleted posts aimed at his estranged wife.

“So dating because I’m single means I’m just worried about d–k?? You sound like a dummy..” she responded. “Trying to be fake nice after you did what you wanted from the beginning trying to push a narrative to these people. Congratulations!! F—k off. Sign the papers TODAY.”

Feb. 14, 2025: Valentine’s Day in Miami

The first confirmed public sighting came on Valentine’s Day, when TMZ published footage of Cardi and Diggs arriving at an undisclosed Miami hotel late at night. It was the kind of blurry, off-hours celebrity sighting that usually means the private part of the relationship is already over by the time the public catches up.

April 13, 2025: Coachella makes it obvious

During Coachella’s first weekend, Cardi was seen giving Diggs a lap dance. Offset later brushed off the video with a comment that “I’m happy for her!!” according to E! News. The tone was less shocking than clarifying. The rumor had become impossible to ignore.

April 27, 2025: Cardi confirms a new man

On X Spaces, Cardi finally let the cat out of the bag without naming Diggs directly. She said she had been seeing someone and framed the relationship in the blunt, defiant language that tends to follow her biggest personal headlines.

“It’s been a couple of weeks and I haven’t addressed nothing,” she said. “Because it’s like … you know when you got a gorgeous n–ga f–king you and loving you from head to toe? It’s like, I don’t really give a f–k what anybody says when you got a real fine n–ga that love you from head to toe.”

May 5, 2025: The Met Gala afterparty sighting

Cardi and Diggs arrived separately at the Met Gala, but gossip site Just Jared reported they were then seen heading into an afterparty within moments of each other. It was another breadcrumb, less decisive than the Knicks game but enough to keep the rumor cycle moving.

May 12, 2025: Courtside at the Knicks game

Then came the outing that essentially made the relationship public. Cardi and Diggs sat courtside at the New York Knicks vs. Boston Celtics game in the NBA playoffs, cuddled up and holding hands as they entered and left Madison Square Garden. It was the kind of celebrity visibility that doesn’t leave much room for interpretation.

June 1, 2025: Instagram official

Cardi made the relationship public in the clearest possible way: by posting Diggs herself. One image showed the pair snuggled together on a boat, and she also shared a steamy video of herself grinding against him. At that point, the relationship had crossed from tabloid matter into Cardi’s own feed, which is often where the real confirmation lives.

Sept. 17, 2025: Pregnancy announcement on CBS Mornings

While promoting her sophomore album, Am I the Drama?, Cardi confirmed she was pregnant and said plainly that Diggs was the father.

“Yes, I am [pregnant],” she said on CBS Mornings. “I’m having a baby with my boyfriend, Stefon Diggs.”

“I’m excited,” she added. “I’m happy. I feel like I’m in a good space. I feel very strong. I feel very powerful that I’m doing all this work. But I’m doing all this work while I’m creating a baby, and me and my man, we’re very supportive of each other.”

For Cardi, who was already raising three children with Offset, it was another intensely public domestic pivot, only this time aligned with the roll-out of a new album and a new phase in her personal life.

Nov. 3, 2025: Diggs says it’s a boy

At the 2025 CFDA Fashion Awards, Diggs told People their baby was a boy. He said the arrival was coming “real soon” in another interview with Extra from the same event, adding, “Wish us both luck.”

Nov. 13, 2025: Their son is born

Cardi announced the birth of her baby boy with Diggs on Instagram, using a video soundtracked by “Hello” from Am I the Drama? Her caption tied the birth to a broader reset, describing the moment as part of a new season and a fresh chapter.

“My life has always been a combination of different chapters and different seasons,” she wrote in part. “My last chapter was the beginning of a new season. Starting over is never easy but it’s been so worth it! I brought new music and a new album to the world! A new baby into my world, and one more reason to be the best version of me, one more reason to love me more than anything else or anyone else so I can continue giving my babies the love and life they deserve. This next chapter is Me vs. Me!”

Nov. 19, 2025: First baby photos

A few days later, Cardi shared photos of her newborn son in his nursery, including one where he was dressed in a Patriots cap and blanket. She also posted an image of herself and the baby cuddling with Diggs while they were still in the hospital, a small but unmistakable reminder that this relationship was becoming part of the family archive.

Dec. 25, 2025: A holiday spent apart

By Christmas, Cardi and Diggs posted separate holiday photos, and fans quickly connected the dots. On Cardi’s post featuring the new baby and her three older kids, Diggs commented, “Miss yaw!!! Don’t be squeezing him too tight you making him soft.”

His own Christmas posts drew attention for another reason: he posed with two different babies, which seemed to line up with reports that he had welcomed children with two other women within the same year as his son with Cardi.

Dec. 28, 2025: Cardi shows up at the Patriots game

Cardi made another public appearance in support of Diggs, this time at the Patriots’ end-of-year game against the New York Jets. She arrived in a pink Chanel look and later joined him on the field, extending the relationship into another very public setting.

Dec. 29, 2025: Cardi pushes back

After Diggs’ Christmas posts revived discussion about his other relationships, Cardi went on X to tell people to back off. Her frustration was plain, even if she delivered it with the same offhand bluntness that has long made her online comments travel.

“Y’all been dragging me for three or four days, and y’all been a little too mean,” she said, laughing. “I can’t change s–t. I can’t go back in time. I already had a baby. Y’all want me to put my baby back in my p—y? You want me to leave my man and f–k yours? What y’all want me to do? We can only go forward now.”

Feb. 3, 2026: The marriage question

On Super Bowl LX Media Day, Diggs was inevitably asked whether he might propose. He kept the answer loose, but not dismissive.

“It’s on the agenda, maybe,” he said with a laugh. “Right, I gotta get mine first, though!”

He also said he had a favorite song by Cardi, though he didn’t name it in the report.

Feb. 15, 2026: A possible split

After fans noticed the pair had seemingly unfollowed each other on Instagram, Cardi appeared to confirm a breakup during a Little Miss Drama Tour stop, saying, “Just because I ain’t f–king with my baby daddy doesn’t mean you get to talk about my baby daddy.” The moment landed in the middle of another public flare-up, this one involving BIA, who had posted on X, “Can u name someone with more [baby mamas] than receiving yards, I can!”

April 8, 2026: Diggs shows up again

Two months later, Diggs attended Cardi’s concert in Washington, D.C., then appeared at her afterparty. Whatever the state of the relationship behind the scenes, the public read was simple: they were at least back in the same places.

May 9, 2026: A Mother’s Day appearance

Most recently, the two seemed to be on good terms at a Mother’s Day event hosted by Diggs’ Diggs Deep Foundation. In a video that spread online, they posed for photos together while Diggs kissed Cardi on the cheek and held her hips. For a couple whose relationship has moved through rumor, confirmation, pregnancy, separation talk, and a baby, the timeline has already become its own kind of entertainment archive.
