The rapper expressed her love by giving him a hug.
Offset shared video of the engagement and Cardi B's diamond ring on his Instagram story shortly after their performance.
"She said yes," he captioned the video.
Cardi B also shared a photo of herself holding up the ring on Instagram, writing, "Jesus Christ I'm so emotional, @offsetyrn I love you so much. Thank you for seeing the potential in me since you met me. For giving me advice molding me and loving me.
Cardi B and Offset started dating earlier this year.
