Cardi B announced Wednesday that she is pregnant with her fourth child and her first with boyfriend Stefon Diggs, telling CBS Mornings host Gayle King that the baby is due in February.

"I'm having a baby with my boyfriend Stefon Diggs," the 32-year-old Grammy winner said during the interview. "I've been putting in all this work, but I'm doing all this work while I'm creating a baby." She said she and Diggs are "very supportive of each other" and described being "in a good space" personally and professionally.

Cardi B confirmed her relationship with Diggs in June, and the announcement comes roughly four months after the pair publicly acknowledged their romance. The rapper, born Belcalis Almanzar, shares three children with her former husband, Offset; she said this will be her fourth child.

Stefon Diggs is best known as an NFL wide receiver. Cardi B spoke on air about balancing career demands with pregnancy, saying she felt "really great" and that she and Diggs were aligned in their professional lives. She did not provide additional details about the pregnancy or the couple's plans.

The announcement adds to a string of high-profile celebrity pregnancies that have drawn attention this year. Cardi B rose to mainstream prominence with chart-topping music and has maintained a public profile through social media, music releases and television appearances. Her discussion on CBS Mornings marks one of her most public confirmations about her personal life since she and Diggs began appearing together publicly earlier this year.

Cardi B's statement on CBS Mornings was brief and focused on the couple's happiness and mutual support. She did not discuss a wedding or other family details during the segment, and representatives for Cardi B and Diggs did not immediately provide further comment.

More information about the pregnancy, including whether the couple has revealed the expected sex of the child or plans for maternity leave, was not available Wednesday. The couple's publicist or team could provide updates as they choose to do so.
