Kate Hudson knows if you've got it, flaunt it.

The 37-year-old actress took that piece of advice to the next level on Thursday, as she flaunted her birthday suit, all in the name of #ThrowbackThursday.

The racy shot, posted to her Instagram, shows Hudson's derriere as she poses naked next to a window. The snap, taken by photographer Darren Ankenman, appears to be an outtake from a photoshoot for Hudson's new book, Pretty Happy.

"#tbt," the mother of two wrote on Instagram, along with the risqué pic. "#PrettyHappy #LOVE #AlmostFriday."

This isn't the first time we've appreciated Hudson's backside. In January, the Rock the Kasbah star was caught lounging naked in a bathtub by her stylist, Sophie Lopez.

"#JustAnotherDayAtTheOffice," Lopez captioned the cheeky shot, posted to her Instagram. And while we were definitely surprised by the pic, it seems Hudson took the post with a grain of salt. "Omg! You're so fired! #Fabletics," she joked back.

Lopez isn't the only fan of Hudson's now-famous booty. Hudson's Mother's Day co-star, Jennifer Aniston, got a little squeeze in at the 2015 Golden Globes.

"Look, girls are cuddly," Hudson later explained of the goose caught on camera. "You know, we're tactile. We like to squeeze and touch and hug and snuggle. It doesn't mean it goes any further. It just means that we like to get cozy."
