Lily Collins is keeping us on our toes! The Dig actress, who shocked fans Friday with a new blonde 鈥榙o that had her practically twinning with Suki Waterhouse, pulled an equally shocking move the very next day, when she snapped a selfie sporting her naturally brunette locks once more.

Her hair change, while major, appeared to be the real deal, with dark, natural-looking roots poking out from her new flaxen locks.

Not sure if it's the blonde or this city, but I really am having more fun...

鈥淣ot sure if it鈥檚 the blonde or this city, but I really am having more fun鈥︹ she wrote. Just a short 24 hours later, however, it was back to business as usual.

Just kidding! Natural locks, back in place. For now...

鈥淛ust kidding!鈥 she said. 鈥淣atural locks, back in place. For now鈥︹ While it鈥檚 unclear if the initial transformation was the result of some serious hours in the stylists鈥 chair for an actual dye job, or if it was only ever a wig to begin with. Our money鈥檚 on the latter, however, as the star鈥檚 actual stylist, Gregory Russell, who regularly posts pics of his handiwork, didn鈥檛 seem to be taking credit for this one.

Instead, he showed off the silky, straight side-part he did for his client鈥檚 walk on the red carpet for the 2018 Breakthrough Prize at NASA Ames Research Center event last night. No matter 鈥 girl looks gorgeous in any color!
