The 33-year-old was spotted on a shopping date with sisters Kim and Kourtney Kardashian at Westfield Topanga Mall in Los Angeles on Thursday, January 11.
But it seems like Kourt and Koko had ulterior motives in taking their sis to the mall as midway through their trip, the gals surprised Kimmy by participating in a flash mob.
TMZ reports that the sisters had planned the surprise in advance for Kim's benefit and her reaction was priceless.
We're assuming that the hilar event will be documented in a future episode of Keeping Up With The Kardashians, but in the meantime you can check out a clip of the dance riiiiiight HERE.
