.Chicago rapper King Yella has a history with Offset's fiancée.
In early 2016, he dropped a track called "Cardi B" which had a video featuring Cardi.
Yella recently IG posted a photo of him and Cardi with the caption "We had yo bitch first." It was @offsetyrn and @iamcardib.
Yella has since deleted the post.
Maybe Offset contacted him and they had a discussion. That's what the Migo did recently when Ugly God posted something that seemed to be disrespecting his bride-to-be.
