When 22-year-old singer, model and actress Sky Ferreira posted a photo of her new haircut with the caption: “THE RACHEL IS REAL”, her fans got very confused.

Why? Because they didn’t know who Rachel was, or what The Rachel is.

Apparently Rachel Green’s haircut from the first few seasons of Friends is still the most requested haircut around – but only if you’re above the age of 20!

Miley Cyrus's little sister Noah was among the bewildered young 'uns, and Miley was so shocked that she posted a screenshot of the message she got from her after sending her a photo of Sky’s new haircut.

There is also a string of confused comments on Sky’s Instagram post, which have to be seen to be believed.

We’ll just be over here so, in our rocking chairs and slippers. How did this happen so soon?!
