Olivia Munn matches baby Malcolm in overalls during vacation with John Mulaney

We can’t get over these mommy-and-me overalls.

Olivia Munn twinned with 18-month-old son Malcolm during a family vacation in Idaho with partner John Mulaney, with the duo matching in khaki bibs, white T-shirts and work boots.

Munn, 43, showed off the looks (and more sweet moments from the trio’s outdoorsy trip) on Instagram Friday, adding the caption, “IDAHO.”

While the actress lounged in her trendy tan overalls, Danner boots and white crop top, her toddler posed in his pint-sized Carhartt pair and tiny Timberlands.

Munn also captioned an Instagram Story of the pair walking through a field, “Matching my little Malc.” 

“The matching is NEXT LEVEL,” one fan wrote in the comments.

“All the pics are awesome.. however those matching dungarees,” another agreed.

“Was John not allowed in the overall club?” asked a third.

Indeed, while Mulaney, 40, is pictured in several of the snaps, he didn’t coordinate his clothes with the rest of the crew.
