The reality star's sisters Kourtney and Khloe threw her a traditional hen party, forcing her to wear an illuminated tiara, drink from a penis-shaped straw and partake in a heavy amount of drinking.
"My sisters are doing everything they can to embarrass me," Kardashian shouted to the crowd, after being forced to receive a striptease from a miniature male stripper.
Humphries was enjoying his own bachelor party close by with future brothers-in-law Rob Kardashian and Lamar Odom when his fiancée decided to attend.
Kardashian shocked Humphries by gatecrashing his party around 2am, but only stayed for around ten minutes to give him a public kiss before leaving to continue her night.
Kardashian and Humphries's wedding is reportedly due to take place on August 20.
