The star blew fans away when she shared a selfie on Instagram on Friday - and her hair has never been longer.
Jennifer, 51, was wearing a cropped T-shirt and jeans in the photo which was captioned: "Back to basics."
But it was her superlong hair, not her outfit, which her followers couldn’t get enough of.

The singer's locks fell far beneath her waistband and even out of shot and her fans absolutely loved the new look.
"Your hair," wrote one, while a second commented: "Hair goals," and a third asked: "Can I have your hair?"
Others marvelled at how youthful she looked and quizzed her on her age.
Jennifer's fans loved her long hair
Jennifer's long hair is in stark contrast to an Instagram post just a few days earlier when she had curly hair and a fringe.
Before that, she appeared on social media with a gorgeous voluminous bob. Her hairdresser, Chris Appleton, shared the photo of J-Lo posing on a beach and revealed it was "all about the length" for him.
Jennifer has had just about every hairstyle
Jennifer regularly experiments with her hair but when it comes to her perfect style she told People magazine she feels her best "when my hair is curly and I’m a little bit tan".
The Jenny From the Block hitmaker grew up in the Bronx and says her upbringing still influences her personality… and her hair.
"Everything about growing up in the Bronx influenced me and is still with me today," she said. "I’m still a ponytail, bun-on-top-of-your-head girl, which is all very Puerto Rican Bronx."
Jennifer likes her hair natural too
Jennifer has done a lot more than switch up her hair during the COVID-19 lockdown. Not only has she been parenting - and homeschooling - her 12-year-old twins, Emme and Max, she's been making new music too.
She just released her two-song collaboration Pa'Ti - Lonely with Maluma and she's set to launch her cosmetic line, JLo Beauty, very soon too.
Not only that but she just designed her first handbag for Coach. The special edition Hutton Bag is available from Oct 2.
She said: "Designing my first bag with Coach was a great experience. I really wanted the Coach x Jennifer Lopez Hutton to feel like me. The colorblock leather and polished hardware details are really my style. It's a bag that makes me look pulled together and ready for anything, and I can't wait to share it with everyone."
