Continuing along with their fun-filled Kentucky Derby weekend, Kim Kardashian and mother Kris Jenner were on hand at Churchill Downs on Saturday afternoon (May 2).

Both looking lovely in white outfits with fancy derby hats, Kim and Kris were treated to quite the entertaining race – as Mine That Bird, a 50-1 shot, pulled off the second biggest upset in Kentucky Derby history with a runaway victory.

The night before watching the biggest of horse races, Kim was on duty as host at the Derby Spectacular party at Glassworks.

Competing against former BFF Paris Hilton’s party being held nearby, the E! reality starlet saw quite the turnout at the fete, which cost $125 and up for admission.
