Pretty Proof That Ariana Grande Was Destined to Become a Pop Princess

Even though Ariana was only 15 when this picture was taken, her taste in beauty was evident: her gorgeous curls were appropriately accented with shimmery champagne shadow and jet-black eyeliner.

Thanks to her new role as Cat Valentine on Victorious, Ariana started her long love affair with hair color with a vibrant Princess Ariel red. She kept the rest of her look subtle with peach-colored lips and cheeks.

As Ariana's locks grew, so did the sophistication of her look. Here, she debuted pearly bronzer and thick eyelashes.

Ariana's color palette at the Grammys reminded us of a desert sunset — shimmering gold and copper playing off peach and brick red.

Even though it can be a major challenge to coordinate red lipstick with ginger hair, Ariana did so flawlessly with her cherry pout and va-va-voom curls.

We're kind of jealous of how Ariana flawlessly executed the pin-up look here — and we love that pink statement nail!

Ariana easily switched her maroon locks to a deep chocolate hue, which perfectly complemented her smoky bronze eye shadow.

Ariana accented her beach waves with a flower-child headband, keeping the rest of her makeup soft with a subtle cat eye.

Along with a sweet pink lip, Ariana rocked the ombré trend with blond-tipped tresses.

Ariana took some styling cues from Mad Men with matchy-matchy retro red lips and nails.

Falling flat was not a concern when Ariana straightened her hair as her mane has amazing volume — even when it's sleek.

Again, we spied enviable volume on her now-blond hair. We also can't get enough of that mod-inspired makeup, especially the eye contour and matte pink lip.

Long, oval-shaped nails and even blonder hair finished off this sophisticated beauty look: flawlessly sculpted cheekbones and a neutral smoky eye.

Ariana kept her makeup look simple, focusing on mauve lips and lush lashes. She topped off her superlong strands with a sequined cat-ear headband.

Ariana was spotted with her hair down (a rare moment!) backstage at the MTV Europe Music Awards as she puckered up and got coy for the camera.

Ariana's bronze shadow, cabernet lip, and flowing ombré locks gave off a seriously sexy vibe.

Ariana's beauty look was perfectly polished on the red carpet — her skin was matte and appeared airbrushed, and she sported thick, retro liner that accentuated her almond-shaped eyes.
