Did Cardi Borrow ‘Be Careful‘ From Rapper Pardison Fontaine? @lifeofthepardi Shortly after Cardi B released her new single “Be Careful” on Friday, video allegedly filmed surfaced of artist Pardison Fontaine rapping the lyrics to “Be Careful” over the same beat. This led many to believe Cardi either utilized a ghostwriter for the Invasion of Privacy single or stole the record for her own gain. Not so fast. It’s important to note that Cardi and Fontaine have worked together in the past; the Bronx rapper appeared in one of Fontaine’s music videos.
