The thank u, next singer, who did not attend Sunday’s show due to differences with producers, live-tweeted throughout the majority of the telecast. But the best rap album category had Grande particularly frustrated as Miller’s fifth and final studio album, Swimming, lost to Cardi B‘s Invasion of Privacy — after the Recording Academy invited Miller’s grieving parents to attend the awards show.
Miller, 26, died five months ago from an accidental overdose.
Though Grande, 25, tweeted, “f—” and “trash,” she later clarified that she wasn’t upset with Cardi who was not the “trash” to which she was referring.
“Nothing to do w her. good for her. i promise. i’m sorry,” she later wrote on Twitter.
She told fans in another message: “She’s not at all and that’s not what i meant and u know that.”
A source confirms to PEOPLE, “It has nothing to do with Cardi,” adding that Grande “was very upset” that Miller lost when the Grammys invited his parents attended the show.
Though he did not win, Miller was honored during the In Memoriam segment of the show. His parents, Karen Meyers and Mark McCormick, were also in attendance — and its their presence that most upset Grande.
In response to another tweet about why the Grammys did not award Miller knowing his parents were at the show, Grande wrote, “this. this is what i meant. karen was gonna have a green suit made.”
All of these tweets have since been deleted.

After Cardi’s win, the rapper posted an Instagram with the caption, “WE WON A F— GRAMMY” — and Grande liked the post, sharing three black heart emojis in the comments section.
Miller, whose real name was Malcolm McCormick, died from a combination of fentanyl, cocaine and alcohol on Sept. 7, PEOPLE confirmed. He was 26.
Though Miller’s album was not celebrated with a win by the Recording Academy, his music has been revered since his death.
To honor his legacy and career, his family organized the “Mac Miller: A Celebration of Life” tribute concert in October with Miller’s friends and collaborators like Scott, John Mayer, Chance the Rapper, Anderson.Paak, Miguel, SZA and Ty Dolla $ign performing.
Miller isn’t the only artist who has been nominated for the upcoming ceremony posthumously.
Rocker Chris Cornell, who died in May 2017, won his 16th nomination in the best rock performance category for, “When Bad Does Good.”
The 61st Annual Grammy Awards are broadcasting live from Staples Center in Los Angeles on Sunday, Feb. 10, at 8 p.m. ET/5 p.m. PT on CBS.
