The "Bodak Yellow" rapper shared the startling video on social media, comically narrating the doomed vessel's demise as it disappeared into the waves.
"I can’t believe I’m actually watching a yacht sink," she captioned the clip on Twitter on Saturday, May 28.
"Oh my...it's sinking! Ya'll see that?" she can be heard shouting in the video, before hilariously adding, "They can't do anything? There's no big boat that can save it?"
"It's gone...it's gone. Bye, bye!" she continues, squealing in excitement as the yacht continues to sink.
Cardi clarified there was no one board. There also appeared to be another ship close by watching as the boat sank.
The video earned over 1,000 comments and over 4,000 retweets, with every reaction from fans scolding the rapper for not doing anything to help the owner of the yacht to giggling over her ridiculous commentary.
"It’s gotta be embarrassing to crash and sink your yacht. It’s gotta be humiliating to do it in front of @iamcardib," one user wrote, while another replied, "OK hear me out: a tv channel just for Cardi B narrating as billionaire's yachts are destroyed."
A third commenter agreed, saying: "Cardi's narration skills made this much more enjoyable than i think should be legal ... Please consider narrating nature documentaries!"
It isn't clear if the "WAP" rapper is stateside or if her husband whisked her away on a romantic getaway to a tropical island. Earlier, the mom-of-two shared a series of sultry snaps as she posed for the camera in private jet sporting a colorful two piece, white heels and matching white-framed sunglasses. Their kids did not appear to be with them.
Cardi and the "Rap Saved Me" artist share 3-year-old daughter Kulture and 7-month-old son Wave. She also coparents Offset's children he had in other relationships: Kalea, 7, Kody, also 7, and Jordan, 12.
