Ariana Grande celebrates one-year anniversary of 'Problem'

Songstress Ariana Grande has reflected on the 12 months that followed the release of her smash hit single 'Problem' and described the last year as something she can't put into words.

Writing on her social media page tonight (April 27), the beauty admitted that she's incredibly grateful for every opportunity that has come her way and she loves the way her career is unfolding:

"One year since #problem!!!! what a year it's been. I'll never be able to find the words to fully express my gratitude and appreciation to be able to do what I love and to have the greatest, sweetest, funniest (but actually the funniest....... ever), kindest, most generous and genuine fans (loves) in the world by my side."

She went onto tease fans by suggesting that she's currently in the studio working on brand new material: "Y'all are dream babes and I love you. Here's to more music and memories (I may or may not be in the studio working on it right now)."
