Ariana Grande may not have attended last night's Grammy Awards but definitely made her feelings known about what went down there.

Ari was due to sing at the ceremony but dropped out over a dispute with producers. She watched from home and reacted angrily when Cardi B picked up the gong for Best Rap Album for Invasion Of Privacy. Ariana's ex Mac Miller, who died in September, had been posthumously nominated for his fifth album Swimming and she clearly felt he would have been a more deserving winner. "Trash. F***. Literal bullshit," she tweeted. "THEY INVITED HIS PARENTS OUT. NO," she added, referring to the fact that Miller's mum and dad attended the ceremony. She later deleted the tweets. Luckily it looks like there's no actual bad blood between Ari and Cardi as she clarified that that she wasn't having a go at the rapper specifically. "Nothing to do w [Cardi]. Good for her. I promise. I’m sorry," she posted before deleting that tweet too. Ariana herself was a winner on the night, with her album Sweetener being named Best Pop Vocal Album. Cardi, meanwhile, was overcome with emotion as she accepted her award. She is the first solo female artist ever to win Best Rap Album at the Grammys. The 26-year-old thanked lots of people, including her husband Offset who helped her to finish Invasion Of Privacy throughout her pregnancy with their daughter Kulture. "You, husband, thank you. Nah, seriously, 'cause he was like, you're going to do this album, girl. "We're gonna have this baby, and we're gonna make this album."
