"Nothing to do w her. good for her. i promise. i'm sorry", she wrote. She is also a longtime friend of Nicki Minaj, who famously does not get along with Cardi.
The win was announced during Sunday's pre-show, and despite the pop star's creative differences with Ehrlich, she had nothing but gratitude for her team and fans. "Trash", she continued, and "literal bulls-".
Many fans noticed Grande's reaction before she deleted the tweets and most assumed that her harsh words were directed towards Miller's loss, rather than Cardi's win. She was actually upset that the Grammys invited Mac's family to the event, even though he wasn't the victor.
Mac Miller, real name Malcolm McCormick, was 26 when he passed away at his San Fernando Valley, California, on 7 September a year ago, from a drug overdose. And it appears Ariana Grande wasn't too happy about it. Grande commented on a post pointing this out and then once again deleted her comments where she says that his mother "was gonna have a green suit made".
In a not so typical speech, she joked her nerves were so bad "maybe I need to start smoking w**d".
She added: "I know I'm not there tonight".
Wearing her dark locks straight down onto her bare shoulders, she took to the stage with husband, rapper Offset.
Heading into the evening, Cardi B was nominated for seven awards across major categories, including Album of The Year and Record of the Year for her chart-topping single, "I Like It". "Rest in peace!" she said in a video posted to Instagram.
