Cardi B has reportedly warned boyfriend Stefon Diggs after he welcomed four children with four different women in 2025.
“She’s been very clear with Stefon: if he messes up, if another woman comes forward with a baby after they became official and started a family together, she’s done,” an insider told the Sun in a report published on Saturday.
“She told him plainly that if he cheats or has a child behind her back, it’s over.”
Diggs, 32, welcomed daughter Charliee Harper with Aileen Lopera in April 2025, a son with K’yanna Barber in 2025, and a daughter with Cayy Benji, also born sometime in 2025. Plus, Cardi B gave birth to their son in November 2025.
Lopera dropped a paternity and child support lawsuit against him earlier this month, Page Six confirmed. Lopera’s attorney, Tamar Arminak, previously claimed a paternity test proved that Diggs is the father of Charliee.
“The paternity has been confirmed. Mr. Diggs is the father of the child,” Arminak told us in November, adding that “Mr. Diggs has acknowledged his daughter.”
Still, the “Bodak Yellow” rapper is said to be loyal to the New England Patriots wide receiver, despite the fact that she “hates the drama.”
“Cardi has known since day one that Stefon had a reputation as a womanizer and had seen multiple women in the past, but her love for him is above all of that,” the source explained to the outlet.
“She knows he has been faithful since they made things official and that he’s been transparent about his previous relationships, only seeing her since they committed to each other.”
The insider also divulged that the Grammy winner — who shares daughters Kulture, 7, and Blossom, 1, and son Wave, 4 with estranged husband Offset — “loves” that the NFL star is “not a deadbeat dad.”
“She believes he’s a present, loving, and supportive father,” they shared.
Diggs kickstarted his family in 2016 with the arrival of daughter Nova, whom he allegedly shares with ex Tyler Marie. And according to the Sun’s source, the rapper, 33, has no problem with his large family.
“She sees his children as an extension of the family and enjoys when they’re all together, spending time as one big extended family,” the source shared.
“She doesn’t harbor hate toward Stefon’s exes or the mothers of his children,” they added. “She doesn’t judge — she just wants everyone, especially the kids, to be happy and grow up in a stable, healthy environment.”
She also “does get upset when people talk badly about him, seeing it as disrespect,” a second source for the Sun shared.
“She’s had arguments over how some people address or treat him in public — but she’s learning how to handle it better.” The Sun’s source said that when the rapper “loves, she fights for her man. Period.”
They added, “She talks to him often about how to best navigate situations involving multiple baby mamas and co-parenting. She gives him advice on being the best father he can be, and he appreciates the constant support she shows him.”
Reps for Cardi B and Diggs did not immediately return Page Six’s requests for comment on Saturday.
Cardi B — who filed for divorce from Offset for the second time in July 2024 — went Instagram official with Diggs in June 2025.
She confirmed her pregnancy with the pro athlete — who is set to play in his first Super Bowl next month — back in September. “I’m excited, I’m happy, I feel like I’m in a good space,” she told Gayle King on “CBS Mornings” at the time.
