No expense was spared at Kris Jenner's 60th Gatsby-themed birthday bash. 

The Kardashian matriarch was photographed passed out in the backseat of her car with her much younger boyfriend, Corey Gamble, who was seen covering her face with his hand as they left her birthday bash.

Her famous children joined forces to throw their momager a 1920's themed soiree, which is rumored to have cost $2 million. The sisters took different approaches to the theme as they snapped photos with their mom against a wall of flowers and a couple of burlesque dancers.

Kim, who is currently eight months pregnant with husband Kanye West's second child, showcased her bulging bump in a cleavage-baring dress with sheer sleeves.

Meanwhile, Khloe wore a beaded hooded dress similar to the one that Rihanna wore at the 2014 CDFA Awards; the dress is rumored to cost $16,500.

Khloe recently commented on the dress she wore, posting a statement on twitter saying "Rihanna was my inspiration, no one can do it like she did and I was inspirted by her dopeness, I love Rihanna and I loved my look."

The birthday girl and Kardashian matriarch made sure she was the center of attention, arriving in a black bob wig and a slinky, white, floor-length, long-sleeved gown.

Other guests at the star-studded party included Kylie's boyfriend Tyga and Kim's husband Kanye West.
