Between history-making actresses Oprah, Mindy Kaling, and Reese Witherspoon, there was plenty of star power on the red carpet for the European premiere of A Wrinkle in Time. But it was Witherspoon’s own daughter, Ava Phillippe, who stole the show. The 18-year-old stepped out for the event with a whole new look, officially bidding adieu to her flowing golden locks with a (gasp!) short blonde bob!

Phillippe was elegant as ever in a black and red striped Valentino frock and Stella McCartney heels, but it was her hair that had us doing a serious double take. Gone were the long curls, replaced instead by sleek, one-length tresses that just barely grazed her collarbone.

The teen made the decision in a moment of spontaneity, taking to Instagram Stories with a shot of her shorn ‘do and writing, “Spontaneously chopped! Thank you AJ @thechapelplace!”

Still, planned or otherwise, the move was a big one for the fashion model, whose looks — and hair! — have been compared to Witherspoon’s for years. While she’ll no doubt always resemble her mother, the transformative chop made for a bold statement of individuality, letting the world know, in no uncertain terms, that these women are NOT the same person.
