Dolly Partons fans swear they just saw her doppelgnger, after she shared a picture of her look-alike sister.

On Sunday, the country music icon, 78, who is releasing a cookbook with her younger sister, Rachel Parton George, shared rare photos on Instagram of the two spending time together.

In the snapshots, the sister duo are seen in matching white and light blue outfits while hanging out and enjoying a meal. In the second pic, the pair pose in casual outfits while standing in front of a car.

The best part of creating this cookbook is getting to spend quality time with my sister Rachel We cant wait to share our recipes with you all, pre-order now at the link in my bio! the singer captioned the post.

Shocked fans rushed to the comments section to sound off over the uncanny resemblance between the siblings, blonde hair and all.
