Nicole Richie was the guest on Ryan Seacrest’s KIIS FM radio show on Monday, October 4.
Among other things they chatted about a green smoothie consisting of kale, coconut water, green tea and broccoli and Nicole told Ryan:
"I gave it to Kim and she took one sip, and she thought that I was nuts. She said, 'I cannot believe that you drink this.' She was mortified ... She was like, insulted."
Nicole and Ryan teased Kim with a picture, writing, "You know you want some juice @KimKardashian".
Both, Nicole and Ryan are wearing House of Harlow 1960 sunglasses.
