Must-see: Reese Witherspoon's daughter Ava is seriously her twin

Genes like whoa!

That was our first thought when we stumbled across this adorable pic of Reese Witherspoon and her 15-year-old daughter Ava Phillippe.

The cute mother-daughter duo were chilling before Reese's big Hollywood premiere of Hot Pursuit, but honestly, don't they look like Pinterest-perfect besties headed to prom?

Like most celeb parents, we're sure Reese has discouraged Ava and her brothers Deacon and Tennessee from getting into showbiz, but with those looks and her A-list pedigree -- dad is actor Ryan Phillippe, stepdad Jim Toth is an agent -- we see a bright, famous future for this one!

And, she'll look like this. Lucky!
