Reese Witherspoon and her daughter could easily pass for sisters.

The 39-year-old mom posted an adorable Instagram photo of herself embracing 15-year-old Ava Thursday, showing just how strong a resemblance the blond beauties share. The mother-daughter duo wear similar smiles and almost-identical long, cascading hairstyles.

In the caption, Witherspoon noted that the pair were decked out for the premiere of "Hot Pursuit," her new action comedy, which co-stars Sofia Vergara.

Ava is the oldest of Witherspoon's three children. The actress also has 11-year-old son Deacon with ex-husband Ryan Phillippe, and welcomed 2-year-old Tennessee James with husband Jim Toth in 2012.

Many Instagram users noted that Ava is the spitting image of Reese. "Your daughter is so beautiful, just like you!" read one comment.

Ava posted the picture on her own account with the caption "me and my 'straight-shooter' ❤️," making a reference to a "Hot Pursuit" movie poster that features her famous mom.
