I was surfing the internet — minding reality TV business, as I do — and noticed that a particular blondie didn’t last too long.

It looks likeKourtney Kardashianis done venturing into blonde hair territory, and she’s gone back to her roots.

This change came days afterKhloé Kardashianshared a hilarious series of Instagram storiesexplaininghow people get them mixed up.

Khloé said an easy way to tell them apart is their hair since Kourtney is a brunette 99% of the time, and she’s a blonde 99% of the time. Ironically, Kourtney was blonde at the time of the post.

Not anymore! The 44-year-old reality TV star has switched back to her signature style, and it looks great on her.

This comes only a few months after shedebutedher platinum blonde hair alongside her son, Reign Aston, 8, who she shares with her exScott Disick.

According to Kourtney’s Instagram story, the last time she went blonde was when she was ateenager, unlike her sisters Kim and Khloé, who seem to switch up blonde every few months.

Kourt’s black bob is part of her signature look. The reason behind the comeback is unknown, but I’m going to guess it’s just in time for the premiere of Season 3 ofThe Kardashianson May 25.

And here’s her official debut!

Welcome black, Kourtney!
