During an album stop on Hot 97, Jack Harlow was played the Brandy track "Angel in Disguise" and was asked whose song it was.

When he couldn't guess, he was given a hint:  It was Ray J's sister's.  It was then he learned that Ray J and Brandy are siblings.

“Who’s Ray J’s sister?” Harlow asked. “Brandy and Ray J are siblings? Nobody’s ever told me that in my life!”

Some people were legit mad about Harlow's ignorance.  India. Arie ripped the 24-year-old for not knowing what was popular when he was very young.

“If U dont know Brandys voice when you hear it …. WHO EVEN ARE YOU? When an ACTUAL MUSICIAN! WHO MAKES BLACK MUSIC! Deduces ones of the industries MOST IMPORTANT VOICES! @brandy To Ray Jays SISTER who is famous (mostly) for his Proximity to Kim Kardashians," she screamed on IG Stories.

For her part, Brandy is taking the snub with better humor.

“I will murk this dude in rap at 43 on his own beats and then sing is ass to sleep,” she typed on Twitter. "See, I can have a little fun too. hehe…all love.”

Is it a big deal Jack Harlow doesn't know the personal history and full catalogue of Brandy?
