While she may have been wearing flip-flops and Givenchy sliders for comfort, of late, Kim opted for a touch of glamour on the night, with a pair of strappy heels.

The brunette beauty sported the perfect black manicure and pedicure as she made her way into the venue and wore her dark hair up in a slicked back high ponytail.

Kim is expecting a little boy with her rapper husband, and she has been keeping his name under wraps for now.
