The internet is now going crazy over Reese Witherspoon's lookalike son!

Reese Witherspoon's kids certainly take after their mum!

And while we already knew that Ava, 17, was the spitting image of her mum, we didn’t know her son Deacon, 13, had been blessed with the exact same genes!

The Academy Award-winning actress shared a photo of her two eldest kids in celebration of her 41st birthday last week.

"There's nothing better than celebrating my birthday with my wonderful kids!#ProudMom," she wrote, along with heart emojis.

Followers were quick to point out Deacon's strong genes, saying he's "the spitting image" of Reese.
