Cardi B reportedly warned her boyfriend Stefon Diggs, with whom he has four children with four women, in 2025.
“She’s been very clear with Stefon that if he fails, if he officially takes office and starts a family together and another woman comes forward with having a baby, she’s done for,” a source told The Sun in a report published Saturday.
“She made it clear to him that if he cheated on her or had a child behind her back, it was over.”
Diggs, 32, had a daughter, Charlie Harper, with Eileen Lopera in April 2025, a son with Kyanna Barber in 2025, and a daughter with Kayi Benji, also in 2025. Additionally, Cardi B gave birth to a son in November 2025.
Lopera dropped the paternity and child support case against him earlier this month, Page Six confirmed. Lopera’s lawyer, Tamar Alminak, previously claimed that a paternity test proved that Diggs was Charlie’s father.
“The parentage has been confirmed. Mr. Diggs is the father of the child,” Alminak said in November, adding, “Mr. Diggs recognizes his daughter.”
Still, the “Bodak Yellow” rapper is said to be loyal to the New England Patriots wide receiver despite “hating drama.”
“Cardi knew from day one that Stefon had a reputation as a womanizer and had dated multiple women in the past, but her love for him was so much more than that,” a source explained to the magazine.
“She knows that he has been faithful since they officially announced their relationship, and that he has been transparent about their relationship thus far and has only met her since their commitment to each other.”
The source also revealed that the Grammy winner, who shares daughters Culture, 7, Blossom, 1, and son Wave, 4, with her estranged husband Offset, “loves” that the NFL star “isn’t a deadpan dad.”
“She believes he is a loving and supportive father,” they shared.
Diggs is said to have started a family in 2016 with the birth of his daughter Nova with ex Tyler Murray. And The Sun’s sources say the 33-year-old rapper has no issues with his extended family.
“She sees her children as an extension of her family and enjoys having them together and spending time together as one big extended family,” the source said.
“She harbors no hatred toward Stefon’s ex-girlfriend or the mother of his children,” they added. “She doesn’t judge. She just wants everyone, especially children, to be happy and grow up in a stable, healthy environment.”
She also “gets angry when people say bad things about him because she thinks it’s rude,” another Sun source said.
“She has had arguments over how people address and treat him in public, but she is learning how to deal with it better.” A source for The Sun said the rapper “when she loves, she fights for her husband. Times.”
He added, “She often talks to him about how to best navigate situations involving multiple baby mamas and co-parenting. She gives him advice on how to be the best father he can be, and he appreciates the constant support she shows him.”
Representatives for Cardi B and Diggs did not immediately respond to Page Six’s request for comment on Saturday.
Cardi B, who filed for divorce from Offset for the second time in July 2024, opened an official Instagram account with Diggs in June 2025.
She confirmed in September that she was pregnant with a professional athlete who is scheduled to play in her first Super Bowl next month. “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.
