Are Reese Witherspoon and Ava Phillippe Secretly Sisters and They're Just Not Telling Us?

Reese Witherspoon and her look-alike daughter, Ava Phillippe, got all glammed up for the Molly R. Stern x Sarah Chloe jewelry launch dinner in LA on Monday night. Upon their arrival, the duo flashed a few smiles and struck their best poses on the red carpet, and things only got cuter when Reese took a moment to fix Ava's necklace.

Ava rang in her 18th birthday back in September, and we've seen so much of her since then. Not only did she celebrate her mom's big Emmys win at HBO's annual afterparty, but she then accompanied Reese to the WSJ. Magazine 2017 Innovator Awards before jetting off to Paris to attend her first-ever Bal des Debutantes. Something tells us we're going to be seeing a lot more of Ava in 2018, and we're not mad about it!
