Wait, who is who?

Reese Witherspoon shared a sweet birthday message on Sept. 9 for her daughter, Ava, who looks more like her mom than ever.

“Wow! My sweet girl turns 16 today!” Witherspoon, 39, wrote. “I am so blessed to have such a kind, compassionate, brilliant, artistic, all-around wonderful daughter who makes me a better person everyday.”

The split image that accompanied the note shows a younger Ava, whose dad is Witherspoon’s ex-husband, Ryan Phillippe, on the left and an all-grown up teenager on the right. In fact, the birthday girl’s recent pic had Us doing a double take.

Is that Reese? Or is it really Ava? With her long blonde hair, arched eyebrows, and heart-shaped face, Ava and her mom really do bear an uncanny resemblance.

If you’re still not sure, take a look at a then-16 Witherspoon from her movie debut in 1991 in The Man in the Moon.
