 The 35-year-old reality star was snapped leaving sister Khloe Kardashian's 32nd birthday party on Monday night at Dave & Buster's in Los Angeles, where paparazzi camera flashes exposed her butt pad underneath her skin-tight pencil skirt. [photo below]

Still, that didn't stop Kim from flaunting her derriere on Instagram that night, having tons of fun playing the arcade games.

Kim's clearly feeling confident these days after shedding 60 pounds since giving birth to son Saint last December, showing lots of cleavage on Tuesday night at GQ's 10th annual Love Sex and Madness celebration at The Nice Guy in Los Angeles. Kim wore a choker and went braless, donning a racy, black lace-up top to the event.
