The Power singer took to social media to declare that she has “had the chop”.
The image showed the 27-year-old sporting platinum blonde should-length locks in a poker-straight cut.
She captioned the post: “She’s had the chop.”
Fans gushed over the new look in the comments with many hailing the look “powerful.”
One user wrote: “Love this look Jesy! so pretty!”
Another commented: “Damn Daniel, back at it again with the killer looks @jesynelson.”
A third added: “I DROPPED MY PHONE AND MY CHICKEN WHEN I SAW THIS.”
Meanwhile, a fourth posted: “Wow you look absolutely stunning as always even with short hair.”
However, others speculated if the hair was simply a wig ahead of the group’s release of brand new single Woman Like Me.
Nelson previously left fans envious of her “stunning” bikini snaps after she enjoyed a holiday at the Maldives earlier this year.
The singer had been soaking up the sun on the Indian Ocean with her boyfriend Harry James.
Nelson shared a picture of herself paddling in crystal waters while posing in a blue bikini. She captioned the shot “paradise”.
She later uploaded a second of herself looking out to see on a swing.
Fans praised her for helping to encourage body confidence in young girls with many saying she had given them “body goals.”
