On a family trip to Idaho, the actress and her toddler wore similar overalls.

The 42-year-old actress posted a picture of her and her 18-month-old kid on “a family vacation” in Idaho with John Mulaney on Instagram on Friday.

In a few of the pictures, Munn wears brown overalls to match her son. In one image, the pleased mother can be seen walking in front of Malcolm while her legs are spread out.

Munn captioned a photo she shared on Instagram Story of her and her son traversing a grassy field, “Matching my little Malc.”

She commented, “I did this,” next to another image.

During a recent family vacation, Olivia Munn matched her son Malcolm in overalls.

“My little boy. Thank God for you,” Munn said beside a close-up picture of Malcom in another Instagram Story post.

A different uploaded video shows the young child having fun fishing with his father at a nearby lake. In a another image, Munn and Mulaney, both 40, can be seen grinning with Malcolm as the three of them sit close to the ocean under a sunny sky.

In a sweet last image, Malcolm is seen smiling and laughing outside while donning a puffer coat and a cuddly fur hat with bear ears.

After Munn posted a Father’s Day tribute to Mulaney last month, her family went on vacation.

Munn was seen in front of the camera assisting the cheerful toddler with his lines—or, more precisely, the line “Happy Father’s Day”—after first sharing an Instagram Reel of the comedian and their baby.

The Big Mouth voice actor grinned and bestowed a big kiss on the young child after Malcolm celebrated his dad with loads of support from mum.

On her Instagram Story, the X-Men: Apocalypse actress posted the endearing clip along with the caption, “Every day for the past 18 months these two fall more in love with each other. I’m lucky to have you as my son’s father.
