Um … we'll have whatever Juliette Lewis is having.

It's clear the 41-year-old has been working hard on her fitness — and her latest photo has our jaws on the ground!

In the drool-worthy pic, the actress is seen flexing in the mirror while wearing a teeny-tiny workout bra and a pair of stretch pants, her insanely toned abs are in clear view and our jealousy is off the charts.

"Gettin closer to my goal of "light weight body builder"!! Haha. @barrysbootcamp ??⚡️⚡️," she captioned the pic.

With summer time right around the corner, we hope Juliette takes advantage of her washboard abs and spends some time flaunting her bod at the beach!

Lookin' good, girl!
