The Unusual Reason Cardi B Has Been Boiling Onions

A certain Grammy Award-winning rapper sure knows how to get us talking. Cardi B had Twitter in disbelief over the way she cracks her eggs, and in the same breath, the artist had us melting over the heartwarming reason she was learning to cook Hispanic food. Spoilers, per People, it's because she aspires to cook like her grandmother. And then there was that time Cardi B took David Letterman to a bodega to try something new in the form of a chopped cheese sandwich. If you are unfamiliar, rapper Bodega Bamz, who hails from Harlem, called this combination of grilled ground beef, onions, and cheese on a hoagie roll " premier item in New York" while speaking with First We Feast.

While we don't know if Cardi B boils onions for making chopped cheese sandwiches, we do know that the practice features in one of her beauty secrets. And this one might have you shedding a tear or two in the process.

But the rapper apparently also likes to boil onions for an unusual, but really practical purpose. If you've ever wondered how the music artist gets her hair so beautiful, sleek, and shiny, wonder no more.

Onion shampoo
