Lauren Conrad just shocked the heck out of us, and it has nothing to do with Halloween (though her costume was spot-on). The new mom took to Instagram this weekend to reveal a MAJOR hair change: She filmed her long ponytail getting the chop!

The LC Lauren Conrad designer shared a slow motion video showing her hairstylist (presumably her pal and go-to hair guru Kristin Ess) snipping off several inches of her famous golden mane, and it was all we could do to not audibly gasp.

Conrad, 31, appeared to be more than ready for the snip, writing a simple,鈥淏ye!鈥 and attaching a girl waving emoji.

The last time we saw such a significant cut on LC, it was back in 2014 when the lob as we know it was just starting to become the it style. *Sigh* How time flies.

With no further pics uploaded to either Conrad or Ess鈥檚 pages, we鈥檙e not sure what this new cut will look like (is it the lob 2.0? Did she go even shorter with a bob? A Katie Holmes pixie, perhaps?). But we do know we鈥檙e plenty excited to see it!

What do you think of LC鈥檚 new look? Let us know over @BritandCo.
