The comedienne shared another sexy snapshot on Instagram on Monday, putting her bare butt on display during a barre workout with her dog, Chunk.
"Kicking off Chunk's work week," she captioned the revealing photo, where she's standing in front of the mirror with one leg stretched to the side and over her pup's head.
The 40-year-old star is wearing a black T-shirt and black capri pants -- but the leggings have been pulled down in the back to expose her derriere to the camera.
In case you missed it, the former "Chelsea Lately" host has been testing the social media site's limits by posting scantily clad pics from all over the globe.
Back in December, Handler exposed her breasts to her fans in a shirtless snap on the top of a snow-covered mountain. She also dropped trou in a hilarious bathroom selfie to mimic Kim Kardsahian's infamous Paper magazine spread.
"Can you believe more than 2 ass can fit on the same screen?" she wrote alongside the pic at the time. "Guess which one's real. Your move, Instagram."
It's only a matter of time until Instagram takes her latest pic down, so until then, enjoy!
