Reese Witherspoon and her daughter look practically identical in new Instagram photo

With bright red lipstick, chunky earrings and black tops, Reese Witherspoon and her 20-year-old daughter Ava are totally twinning in the star's latest Instagram snap.

The 43-year-old actress posted a photo of the two standing side by side before a fun outing with the caption, "Girls night out with my favorite daughter! (ok she’s my only daughter but still)."

However, despite the matching outfits, fans can't seem to get over how much Ava looks like an exact replica of her mother when she was 20. Witherspoon had just shared a throwback photo of what she looked like in the 90's, showing the striking resemblance with her daughter.

Fans and friends couldn't stop gawking about their doppelganger situation in the comments section, either. Witherspoon's "Big Little Lies" co-star Zoe Kravitz gushed, "omg my lil gorgeous twinZzzzzzzz," while Mindy Kaling hilariously declared, "I fainted."

This isn't the first time people freaked out over the twinning Witherspoon mother-daughter duo. A month ago, the "Big Little Lies" actress posted a sweet lunch selfie with her daughter, which earned similar comments.
