When thinking back on 2018, it's safe to say that this year was one of the best for new music. So many artists released great content and made such an impression on the music world, from Cardi B to Post Malone, Drake to Halsey... and the list goes on.

However, the one person who I think had the biggest year was Ariana Grande. Looking back at the singer's journey in 2018, it's clear she went through more in a single year than most go through in a lifetime. Ariana had many highs, but she also had many lows: Every situation she went through in her personal life was broadcasted in front of the entire world. But in the midst of it all, we watched her grow and come into her own as an artist, as well as truly prove to the world how strong of a woman she is despite the circumstances outside of her control.

In honor of Ariana Grande's iconic year, we've put together a timeline of some of the biggest moments she had in 2018.

On May 22nd 2017, there was a deadly explosion at the end of Ariana Grande's concert in Manchester that left 22 people dead and over 500 people injured. In an interview with Fader earlier this year, Grande revealed how the event still affects her more than a year later. “I guess I thought with time, and therapy, and writing, and pouring my heart out, and talking to my friends and family that it would be easier to talk about, but it’s still so hard to find the words. When you’re so close to something so tragic and terrifying and opposite of what music and concerts are supposed to be, it kind of leaves you without any ground beneath your feet,” she expressed.
