Kim and Kourtney are on their way back from Cleveland, where they were in the room when Khloe gave birth to her baby girl!
Not only were they there, they also helped assist! Kim tweeted that she held Khloe's leg as she delivered her baby.
(Who was holding the other leg? Tristan?)
They ALSO gave her a $7.5k mommy gift basket including blankets, bath and body products and a bassinet! What good sisters!
