A tragic goodbye. On Sept. 7, 2018, Mac Miller passed away at the age of 26. A week after his death, Grande paid tribute to her ex in a moving post on social media. "i adored you from the day i met you when i was nineteen and i always will," Grande wrote. "i can't believe you aren't here anymore. i really can't wrap my head around it."

Thank U, Next. In early November, Grande released her new song, "Thank U, Next." In the track, Grande sings about her exes, including Davidson, Miller, Big Sean and Ricky Alvarez. "Thought I'd end up with Sean / But he wasn't a match / Wrote some songs about Ricky / Now I listen and laugh," the lyrics state. "Even almost got married / And for Pete, I'm so thankful / Wish I could say, 'Thank you' to Malcolm / 'Cause he was an angel."
A tearful speech. In December, Patti LaBelle presented Grande with Billboard's Woman of the Year Award. During her acceptance speech, Grande teared up while reflecting on her year. "This is really special," Grande said. "I want to say that I find it interesting that this has been one of the best years in my career and one of like the worst years in my life."
Vegas cancellation. Shortly before she was set to perform, Grande canceled her New Year's Eve weekend concert in Las Vegas. "Vegas, I'm currently working through some health issues and am beyond sorry I won't be able to see u this weekend," Grande wrote to her fans on her Instagram Story.

Album debut. In February, Grande dropped her new 12-track album, Thank U, Next. On the album, Grande addresses her relationship with Davidson and losing Miller. In "Ghostin," Grande sings about how loss can impact a relationship. "Baby, you do it so well/You been so understanding, you been so good/And I'm puttin' you through more than one ever should," Grande sings. "And I'm hating myself 'cause you don't want to/Admit that it hurts you."
First Grammy. Grande won Best Pop Vocal Album for Sweetener at the 2019 Grammys, but was not in attendance at the ceremony. Grande was actually supposed to perform at the award show, but decided not to after a disagreement with producers. "F--k," she tweeted after her win. "I know i'm not there tonight (trust, I tried and still truly wished it had worked out tbh) and I know I said I try not to put too much weight into these things .... but f--k ....... this is wild and beautiful."
Honoring Mac. Before taking the stage on the opening night of her Sweetener World Tour, fans could hear Miller's songs playing in the stadium.

In Grande's cover story for Vogue, she talked about the many heartbreaking experiences she's faced in recent years. "I'm a person who's been through a lot and doesn't know what to say about any of it to myself, let alone the world," she shared. "I see myself onstage as this perfectly polished, great-at-my-job entertainer, and then in situations like this I'm just this little basket-case puddle of figuring it out...I have to be the luckiest girl in the world, and the unluckiest, for sure."
A possible new romance. In early August, rumors started flying that Grande had a new man in her life, Social House artist Michael "Mikey" Foster, who Grande collaborated with on the track "Boyfriend." The duo sparked relationship speculation following the release of the music video for the song, which showed off their obvious chemistry.
A dream duet. Grande surprised the crowd at Barbra Streisand's Chicago concert in early August when she stepped out on the stage for a duet. The dynamic duo sang the late Donna Summer's song, "No More Tears (Enough Is Enough)."
