Kim Kardashian Peed on That Pregnancy Stick for Free!

Kim Kardashian doesn't usually endorse things for free so Clearblue scored a HUGE free promotion when Kim endorsed their pregnancy test on social media.

Reps for the brand tell us Kim's no brand ambassador and wasn't paid a single penny to rep their digital pregnancy test when she shared her baby #3 scare with the world. Kim's usual starting rate for repping a brand is reportedly a cool $1 million, so that should put things in perspective.

Kim bought 2 other brands, but Clearblue's digital test was the lucky one to make the final cut in her Snapchat ... and apparently it was on the house.
