Ariana Grande went bonkers when she learned that Cardi B won the Grammy, for Best Rap Album last night.

Ariana, who is close friends with Nicki Minaj, flew into a rant of protest when they announced that Cardi won the award that had eluded Nicki for her entire career.

Cardi's album also beat out Ariana's ex-boyfriend Mac Miller's album Swimming. Mac Miller died of a drug overdose last year.

So Ariana's resentment of Cardi's win was two-fold. Here's what she said, moments after Cardi B was announced the winner:

But Ariana Grande isn't the only one calling "bullsh*t" on Cardi B's big win. Twitter seems to agree. While Cardi's album was full of hits - most of them were collaborations with other artists, who mostly carried the track.

Twitter seemed to prefer Nipsey Hustle's album Victory Lap or Pusha T's album Daytona, as the best "rap" album.

In case you're wondering, Ariana has three American Music Awards, three MTV Europe Music Awards, two MTV Video Music Awards and one Grammy Award.

Ariana Grande skipped the Grammy Awards on Sunday despite picking up her first-ever win following a public dispute with the show's producer.

Grande, who won the best pop vocal album trophy for "Sweetener," beating Taylor Swift, Kelly Clarkson, Pink, Shawn Mendes and Camila Cabello, was not in attendance at the pre-telecast ceremony, but she wrote on Twitter that her win was "wild and beautiful."

"I know I'm not there tonight," she tweeted. "Trust, I tried and still truly wished it had worked."
