Cardi B has been hospitalized due to a medical emergency, and has had to cancel her performance at ONE Musicfest as she focuses on her recovery.

The rapper opened up to fans on Twitter, writing "I am so sad to share this news, but I've been in the hospital recovering from a medical emergency the last couple of days and I won't be able to perform at ONE MusicFest."

"It breaks my heart that I won't get to see my fans this weekend and I really wish I could be there," she continued. "Bardi Gang -- thank you for understanding and I'll be back better and stronger soon. Don't worry. Love yall."

Cardi was headlining ONE Musicfest along with Earth, Wind & Fire, Nelly, and Method Man to name a few. The festival's official Twitter account sent her their best, writing "Hey #OMFFam! Unfortunately, @iamcardib announced that she is no longer available to join us this year due to ongoing health issues. Let's all keep her in our prayers for a full recovery! We are working hard to find a replacement at this late date. More to come soon."

Cardi hasn't commented further on the nature of her medical emergency, but we're wishing her all the best as she recovers!
