It looks like Brandy might be throwing shade at her former arch nemesis Monica.

It all started after celebrities like Dwyane Wade and Chance The Rapper took part in the So Gone challenge, rapping over the beat of Monica’s hit 2003 song of the same title.

One fan asked Brandy if she would take part in it and her response was simple and yet possibly shady, “chile bye” she said, according to Fameolous.

She followed it up with another comment. “I already did #TheBoyIsmineChallenge and the #itAllBelongsToMeChallenge so I’m already #soGone.” The Boy Is Mine and It All Belongs To Me were the two songs Monica and Brandy did together. She added, “I just might and see what happens…Hehe…I think we already know… but nah.”

Still, she didn’t end there as she hinted she might start a challenge of her own.

She held up a sign that reads, “Chile, bye!” and wrote the caption, “…this statement has me sooooooo famous again (sarcastic)!! Should I do the #chilebyechallenge for more validation????? Lmao…Or maybe I should drop a single like a remix or something so I can stay on top… #challengesAreTheNewWave---“

Meanwhlie, Monica did the challenge and murdered it. Take a look.

Monica and Brandy have been rumored to be feuding since their teenage years. Monica even admitted in one 2012 interview that she got physical with Brandy back in 1998. Interestingly enough, the two girls were promoting their then new single It All Belongs To Me, and Monica admitted that she did hit Brandy but reiterated multiple times that she did apologize. Check out that awkward moment below.
