No little lies here: Reese Witherspoon and Ava Phillippe are totally twinning in their new selfie. 

What? Like, it's hard? Apparently not for this mother-daughter duo. Because after the Legally Blonde star posted a picture of her and the 23-year-old getting ready for a "perfect summer night" with conservation nonprofit Oceana, fans couldn't help but comment on the family resemblance.

"Literally twins," one follower wrote underneath the July 23 post. Added another, "Who's who?" And a third told Reese that Ava is, "Your mini-me." 

Reese shares Ava as well as son Deacon Phillippe, 19, with ex-husband Ryan Phillippe, and some followers noted they saw more of a father-daughter likeness. 

"She looks like Ryan a lot," one commenter stated. Another agreed, "Ava is a copy of her dad."

Reese also has 10-year-old son Tennessee Toth from her marriage to Jim Toth. The Oscar winner, 47, and the producer, 52, announced their decision to divorce in March after nearly 12 years of marriage.

This isn't the first time Ava and Reese have made fans do a double take.

While enjoying a family summer vacation, Reese Witherspoon and Ava Phillippe posed for a selfie and proved just how beautiful their bond is. 

The Big Little Lies star joked she "had to beg" Ava to rock matching Draper James holiday sweaters. 

Reese and her mini-me daughter served some fresh winter fashion in January of this year in puffer coats.

The two ski bunnies snapped this cute selfie together before hitting the slopes.

The two looked like mirror images of one another in black dresses and a red lip in a post on Reese's Instagram in December of last year.

"Lunch with my girl," Reese captioned this cute candid of the two enjoying delicious-looking salads.

Talk about seeing double! The duo hits the red carpet for season two of Reese's show, Big Little Lies, in May 2019.

The duo celebrates Reese's 43rd birthday! Ava takes to Instagram to send a sweet message to her momma, saying, "You are such a generous, conscientious, and passionately kind person, and I am so blessed to bear witness to your light and love each and every day!"

In October 2018, Reese and her daughter stepped out at a gala in sexy little black dresses and they were totally twinning.

Clearly, Phillippe inherited her mom's killer, blonde locks and power stance.

Witherspoon enlisted her daughter for Draper James' spring collection in 2018 and if her goal was to make us do a double take it definitely worked.

As the duo celebrated Christmas in 2017 they looked cheerful in red.

We know it's hard, but if you look closely these two look related. Oh wait, that's not right...they look like identical twins!

In October 2017, the pair posed for photos in similar, but different ensembles. Notice the wavy locks, peep-toed heels and signature natural makeup looks both ladies rocked.

If it weren't for the Oscar winner's red lipstick, it would be quite the challenge telling these two apart.

It's clear Phillippe inherited her mama's signature grin. 

Another day, another sweet mother-daughter snap of the actress and her lookalike daughter.

Yup, some genetic wizardy was definitely involved here. 

There's no question these two are related, but Phillippe also looks a lot like her dad, Ryan Phillippe, here.

This mother-daughter duo resemble each other down to their shoe choice. 

Even their side profiles match!

Makeup free and fabulous is something both of these ladies are on a regular basis.

In October 2015, Witherspoon and Phillippe had a fun girls' night and proved once again that they are birds of a feather.

Everything about this Mother's Day post makes us happy.

If you've ever wanted to see Witherspoon with blue locks then look no further!

Is it just us, or are we looking at two baby Reeses here?

From their piercing blue eyes to their platinum blonde locks, it was clear from day one that Phillippe was her mom's mini me.
