“Mother daughter time,” Witherspoon, 40, captioned the close-up, along with a string of red heart emojis. In the image, the Oscar winner and her eldest child share the same bright blue eyes, close-mouthed smile and sun-bleached hair.
One small difference between the pair, however, is Ava’s tiny nose ring, which is just barely visible in the sunlit selfie.
In addition to Ava, Witherspoon and ex Ryan Phillippe also share son Deacon, 12; she and second husband Jim Toth are parents to son Tennessee, 3.
In April, Witherspoon proudly told Us that despite their similar appearances, Ava is definitely the “cooler” one.
“She’s very cutting-edge, and she knows a lot about fashion, and she has her own sense of style, which is amazing,” the Draper James founder gushed to Us Weekly at the Tiffany & Co. 2016 Blue Book Gala in NYC.
“We try to confer about new styles,” she added. “[Ava] tells me whether or not I can wear things.”
