We know the Kardashian sister's are close but we weren't ready for this video showing Kourtney Kardashian squirting her breast milk directly onto Kim Kardashian's leg.
Kourtney was actually trying to help heal Kim's psoriasis rash as Kim said putting breast milk on the area had been helping.
But even Kim looked a bit freaked out when Kourt decided to squirt some milk on her straight from the boob.
Breat milk actually has some known soothing qualities so maybe the sister's have found a new cure.
We'll have our eye on Kim's legs from now on to see if the boob milk did the job!
Check out the clip below...
