Cardi B Says Kulture's Excited to Be a Big Sister

Cardi B and Offset are looking pretty damn excited, and maybe a little overwhelmed, after letting the world know baby No. 2's on the way, but someone else is even more excited by the news.

We got Cardi and Offset leaving BOA Steakhouse in WeHo where they hit up a BET Awards after-party. Quavo and Taraji P. Henson were some of the other attendees, but fans and photogs, went wild when Cardi stepped out of her ride showing off her baby bump.

The couple got peppered with dozens of baby-related questions -- really, you'd think they were walking into a family reunion. One question our guy asked was about Kulture's reaction to the news she's gonna be a big sis.

We also asked Offset if he'll be in a giving mood when the baby arrives -- and the answer's yes! He's got a Cuban celebration in mind.

We tried to get some other deets about Cardi's pregnancy ... like how far along she is, cravings, baby names??? They're not ready to spill all that just yet, but they couldn't look happier that their family's expanding.

As we reported, Cardi revealed the huge surprise Sunday night during the BET Awards. She didn't have to say a word ... her baby bump was on display and it did all the talking.
