Ariana Grande (and all her Arianators out there, of course) have a pretty exciting reason to celebrate today. It's the "Everyday" songstress' birthday!

To commemorate this very big occasion, we're honoring Ari by taking a look back at her evolution over the years. If one thing is for sure about Ari's look, it's that it is always changing – and that's one of the many reasons why we look to her as a total beauty icon. From her naturally curly brown hair to her straight red locks during her Nickelodeon days, she's always keeping us on our toes.

After seeing Ari with fiery red hair for so long, we then began to get used to her signature perky ponytail she rocks nowadays – and it's so hard to picture her any differently. However, Ariana used to look totally different in her early teen years. With naturally curly brown strands and a totally more casual style, Ari had an entirely different style. What an evolution!

How old is Ariana Grande?

Ariana Grande is 24 years old, as she was born on June 26, 1993. The singer was born in Boca Raton, Florida, where she grew up before moving to Los Angeles to pursue her acting and music career.

Ari's Hairspray Live co-star Dove Cameron, who she got really close with on set, took to Instagram to share a special birthday message for Ariana. Ugh, the friendship between these two just ever gets old. You can truly tell just how much love they have for one another.
