The saying "respect your elders" is a pretty worldwide mantra, but one famous singer didn't care when addressing the actions of one of her inspirations.
It's none other than Disney actress turned "Confident" pop star Demi Lovato.
It all started when Demi posted a shady comment under an already shady post on Instagram, and it was a mess from there:
Of course, the young singer's comments were not about to go unnoticed by Mariah's notoriously loyal Lambs, who swarmed her comments with lamb emojis and throwing out insults and vulgarities left and right.
In an attempt to explain herself, Demi continued to comment, saying that while the "Vision of Love" star has a huge talent, she "constantly disses people. It's nasty the way she treats Jennifer [Lopez]. Ari did nothing wrong," referencing Mariah's failure to acknowledge Grande's talent despite the constant comparisons of their voices.
Continuing to use MiMi and J.Lo's "lack of knowledge" of one another as an example, Demi said while Jenny from the Block keeps things classy, Mariah "is mean for no reason. Extremely talented? Yes. Superhuman? possibly. Unnecessarily rude? Absolutely."
Of course, the backlash just continued, but she had one message for her haters: "Too tired to give two f***s."
