According to Hollywood Life on Friday, Kris is apparently none too happy that her ex-husband, formerly known as Bruce Jenner, might steal the spotlight away from the Kardashians on Kylie's wedding day.

A source close to the reality television family told the site, "Kris was livid - and she let Tyga really have it! Kris is furious, absolutely furious at Tyga for asking Cailtyn to walk Kylie down the aisle when the time comes for them to get married."

The insider added, "She thinks Tyga's lost his mind and compromised their friendship. She feels betrayed by him, especially since she's been his biggest supporter and friend for years. He should know better than this - Kris is really hurt by his actions."

Meanwhile, according to the Mirror last month, the 17-year-old admitted that she is going through a very rough stage in her life right now because of her father.

She said, "I feel like I go through these times where I hate my life. My sisters keep trying to push me to talk about things but I don't really want to talk to anyone else right now" before her sister Kendall added, "Kylie and I are handling [Bruce's transition] differently. Kylie does bottle up her emotions."
