Jennifer Lopez Tries Out Ariana Grande's Signature 'Do

Splash News

Jennifer Lopez and Ariana Grande go head-to-head in the same voluminous hairdo.

To be fair, Jennifer Lopez probably did it first!

The forever ageless Jennifer, 45, was snapped out and about in New York City Monday, but it wasn't her fitted snakeskin minidress that had people talking -- it was her high ponytail, which was more than reminiscent of Ariana Grande, 21.

Though it's worth noting that Jennifer isn't exactly copying Ariana's now-signature 'do -- she memorably sported that look in her "Love Don't Cost a Thing" video back in 2003.

NEWS: Ariana -- I Wear More Fake Hair Than Any Drag Queen

It's no secret that Ariana likes her hair a specific way, and has commented in the past on why she always appears to wear her hair in the same style. In February, she explained that dying her hair red every other week for four years playing Cat on Sam & Cat has "destroyed" her natural hair.

"My real hair is back to brown and I wear extensions but I wear it in a pony tail because my actual hair is so broken that it looks absolutely ratchet and absurd when I let it down," she explained. " ... So as annoying as it is for y'all to have to look at the same hair style all the time, it's all that works for now (AND I'm comfortable for the first time in years)."

That being said, who looks best in the high ponytail, J.Lo or Ariana?
