Kourtney Kardashian Works A Catsuit At Diddy's Birthday Party

The 36-year-old worked all of her angles in a lacy gold and black unitard.

Of course, her 60-year-old momager Kris Jenner would not miss out on the fun.

The star-studded event took place Nov. 21 at a mansion in Beverly Hills.

For the record, Diddy's actual birthday is Nov. 4, and he's been celebrating all month.

But who really needs a reason to get decked out in their best gear?

The Kardashians certainly don't!
