Takeoff - real name Kirsnick Khari Ball and who was a member of hip hop group Migos alongside Offset and Quavo - was shot dead aged 28 at a Houston bowling alley.
Appearing on the latest episode of the Jason Lee Podcast, the WAP singer and rapper, 30, recalled finding out the devastating news.
She explained that she and Offset, 31, were supposed to be attending a Halloween party in New York held by La La Anthony, but their four-year-old daughter Kulture had been sick all over her costume so they had decided to stay home.
She said: “We just fell asleep and out of nowhere, Offset’s phone kept ringing, my phone kept ringing. Offset picked up the phone and he’s just like, ‘No!’ And he’s screaming and screaming. And I’m like, ‘What’s going on?’ He’s like, ‘Takeoff is dead’.”
The star, whose real name is Belcalis Maerlenis Almánzar Cephus, said she then “smacked” her man shouting at him not to say things like that.
She continued: “He’s just like screaming, throwing things, throwing up, running all over. I was just so scared. I was just crying so much. It was terrible.”
As word of Takeoff’s death spread, Cardi said the mood became extremely sombre, adding: “It was just such a sensitive time in my home. I feel like everything was so triggering. It was a lot.”
Offset - also known as Kiari Kenfrell Cephus - was inconsolable following Takeoff’s death as not only was he his bandmate, he was also his cousin.
Taking to Instagram to pen a tribute, he wrote: “My heart is shattered and I have so many things to say, but I can’t find the words. I’ve been going to sleep and waking up hoping that all of this is a dream, but it’s reality, and reality feels like a nightmare.”
