Kylie Jenner is "devastated" by Jordyn Woods' betrayal.
The 'Keeping Up With The Kardashians' star was shocked to find out her best friend kissed her sister Khloe Kardashian's boyfriend Tristan Thompson and is upset at the idea she will have to cut her off.
A source told The Sun Online: "Kylie is devastated about everything. She would never have guessed this would happen. Jordyn is her closest friend and she relies on her so heavily. She gets advice on everything from her - Jordyn goes to pretty much every business meeting with Kylie.
"They live together, she helps care for Stormi, she drives her places, she is emotional support when Kylie is overwhelmed. Faced with losing all of that, Kylie is really upset. She's been in tears every day and the whole family is very concerned she won't be able to cope without her."
Jordyn was recently told to move out of her best friend Kylie's house so that the television personality can make up her mind about what she wants to do next.
