The single mum-of-three, 36, attended the birthday party of rapper Sean 'Diddy' Combs on Saturday night (21 November) - and our legs went a bit wobbly when we saw these pictures of her outfit!!!!
The eldest of the Kardashian-Jenner siblings, Kourtney looked jaw-droppingly good when she arrived at Sean's 46th birthday party alongside her mum Kris Jenner.
Dressed in a sheer black bodysuit with gold sequins which showed off every inch of her frame, it's clear all those hours in the gym have paid off.
Don't forget the Keeping Up With The Kardashians star only had her third child less than a year ago!
While Kourtney gave us serious body goals, her mum Kris looked super chic in a white dress.
Kourtney's supermodel sister Kendall Jenner also partied at the glam event, with friends Cara Delevingne and Gigi Hadid.
Could this party BE any more glam?
Sharing a photo of herself with her stunning pals, Kourtney joked: "Just us supermodels."
The night out came after Kourtney called her ex-boyfriend Scott Disick an a***hole in footage from KUWTK.
In teasers for Sunday night's episode (22 November), she is heard crying on the phone with her mum as she explains why she and Scott broke up.
She says: "He flaked on going to the kids' first day of school. He says: 'I can't go because I hate school s**t, I get anxious.' When really he went out and partied through the next day, just like a real f***ing a***hole."
