Ariana Grande was quick to tweet and delete "Trash" after Mac Miller lost the Grammy for "Rap Album of the Year" .
Ariana felt snub was a sign of total disrespect from the award show to the late rapper and his family.
Mac Miller, who died in September had received the first nomination of his career for Sunday's show for his album "Swimming." Mac was up against Travis Scott, Nipsey Hussle, Pusha T and Cardi.
Grande tweeted "Trash" after Cardi was announced the winner but clarified the shade wasn't at Cardi, saying, "Nothing to do w her. good for her. i promise. i'm sorry."
Ariana was upset because the Grammys flew Mac's parents out for the show which to her was a sign he was likely going to win and she felt they disrespected him by giving it to someone else.
Ariana was not only suppose to attend, but she was suppose to perform, but producer, Ken Ehrlich and Ariana could not see eye-to-eye about song choice and told Ariana that her latest single "7 Rings" wouldn't connect with the audience, so he asked her to choose a different song. Ariana felt strongly her choice was what people wanted to hear, and when Ehrlich wouldn't budge, she decided to back out.
