In a new clip from a two-part special of Keeping Up with the Kardashians, Kris Jenner is in tears after learning of the news from Bruce. Jenner:

He’s the most amazing person I know. I couldn’t ask for a better dad. He taught me how to ride a bike and be the tomboy that I am…He would drive us to school and he would be the first one in line to pick us up.

Kim explains:

He has to deal with this for his entire life of waking up and feeling like ‘whoa, this isn’t my body. This doesn’t feel comfortable.
