The blonde beauty - who is BFFs with Lauren Conrad - was previously rocking sleek, smooth and super-long locks which fell way past her shoulders.
But it seems she fancied freshening up her bonce a bit, and what better way than by opting for this year's must-have haircut?
The likes of Ashley Tisdale, Vanessa Hudgens and Kylie Jenner have all championed jaw-skimming locks and now Lo is in on the action too.
Taking to Instagram yesterday (17 September), the reality star posted a snap of her mane post-haircut, showcasing a new length which barely grazed her shoulders while opting for blunt tips to add body and thickness.
But her transformation isn't finished just yet as Lo hinted there's a dye job still to come!
Alongside her snap, the starlet wrote: "Sneak peek - cut comes first, colour comes next! Can't wait to show you the finished new look for fall! Stay tuned! anderssonjj @riawnacapri."
We wonder what hue she'll go for... autumnal chestnut brown? Beach-ready platinum blonde? Fiery festive red? We guess we'll have to wait and see!
