Caitlyn Jenner recently went public with her new girlfriend, 22-year-old student and fellow transgender woman Sophia Hutchins.

While she appears to be head over heels in love with her new lady, one person isn't co-signing her now pretty public romance: her youngest daughter, Kylie Jenner.

According to Radar Online, Kylie is sick of Caitlyn gushing about her new relationship with Sophia, who is just two years older than the beauty mogul. The site reports that their romance is making her sick.

"Cait couldn't stop talking about Sophia, her beauty and how much she's into fashion and makeup and even suggested to Kylie [to] hire Sophia to work on her cosmetic lines," an insider told the site.

That moment was reportedly when Kylie had enough and spazzed out on her father.

"Kylie wasn't hearing any of that and told Cait Sophia's too young and only in the relationship for the money," the source continued. "Cait took offense to that and explained to Kylie that Sophia is the most honest, open and understanding woman she's ever been with in her life. Kylie took that as a diss to her mother and they dropped the subject."

The site further reports that Caitlyn has been blowing several thousands of dollars in cash a week on Sophia to keep her up to date on the latest fashion trends.

"She's constantly treating her to drinks and dinners at the nicest restaurants in town and buys her jewelry and handbags all the time," the insider added. "This is costing Caitlyn at least $50,000 each week but she thinks nothing of this weird arrangement."
