Cardi B might have looked like she was wearing a wedding dress [1] when she arrived at the 60th annual Grammy awards [2] on Sunday night, but her date wasn't her fiancé and fellow rapper Offset [3]. Instead, the "Bartier Cardi" singer brought along her look-a-like sister, Hennessy Carolina Almanzar, who shone just as bright as her older sister in a sparkly floor-length gown.

For those who aren't fans of Love & Hip Hop: New York, you might not recognise Hennessy, but the 22-year-old appeared on seasons six and seven of the reality show alongside her sister. While Cardi has been busy blowing up the music scene as one of the most in-demand new rappers, Hennessy has become a star in her own right. She currently has 1.7 million Instagram followers [4], and has parlayed her social media fame into hosting club events and working toward starting her own fashion line [5].

No matter how busy both Cardi and Hennessy have gotten as their careers take off, it's clear they make plenty of time for each other — they regularly pop up on each others' Instagrams and attend music industry events arm-in-arm. Oh, and if you ever doubt how close they really are, just take a look at their names. Cardi — real name Belcalis Almanzar — actually chose her stage name because people nicknamed her Bacardi growing up as a nod to her sister's alcohol-themed name.

My name is Belcalis ,Growing up people called me Bacardi cause my sister name is Hennessy ..FYI
