Okay, we get it! Kourtney Kardashian is the oldest Kardashian sister and a mother of three, but that doesn't mean she's not hot as hell, damnit!

The 38-year-old strutted her stuff Friday as she left a Burbank studio, wearing a lace crop-top cami with a white button-down draped around her shoulders, ripped jeans and Gianvito Rossi heels. Her look screamed "Hey, look at me! I'm hot!"

KK recently returned from vacation in Egypt with boyfriend Younes Bendjima but now that the couple's back in LA, the male model was spotted out with 18-year-old Sofia Richie this week at lunch, holding hands!!! Kourtney's gotta get her man's attention ASAP before he switches gears and goes for the younger girl. What better way to do that than wearing lingerie in public!
