They're twinning! Ageless beauty Reese Witherspoon just had a seriously doppelgänger moment with her 16-year-old Ava Phillipe when the Oscar-winning mom posted a sweet selfie with her daughter on Friday, July 8.

The photo, which the 40-year-old posted on Instagram, showed the uncanny resemblance between the mother and daughter duo had us doing a double take.

The "Big Little Lies" actress captioned the photo, "Mother daughter time."

Mother daughter time ❤️❤️❤️❤️❤️❤️❤️❤️

The photo shows a close up the "Wild" actress and her oldest child's sun-kissed faces. Ava shares the star's smile and piercing blue eyes. Of course, there is one difference -- the teen has a tiny nose ring, which the mom of three has opted not to get!

The hands-on mom, who is spotted out and about with her three kids on the reg, can't stop gushing about her Mini-Me daughter -- and who could blame her?

Reese, who formed her own clothing brand Draper James, boasted to Us Weekly about Ava's flair for fashion at the Tiffany & Co. 2016 Blue Book Gala in NYC on April 17.

"She's very cutting-edge, and she knows a lot about fashion, and she has her own sense of style, which is amazing," the proud mom told the mag.

"We try to confer about new styles," she added. "[Ava] tells me whether or not I can wear things."

The "Legally Blonde" actress also told the publication that Ava is by far the "cooler" one out of the two. We've seen Ava's Instagram -- so we'd definitely have to agree!

Ava is Reese's first child with her ex Ryan Phillippe, whom she was married to from 1999 to 2007. The exes also share son a 12-year-old son, Deacon. The young mom and her second husband, CAA agent Jim Toth, also have son Tennessee, 3.

congrats! #specialnight
