Kendall Jenner has found herself in the firing line. Her current boyfriend's ex has filed a lawsuit against him, alleging Jenner of ruining their relationship.

Public Humiliation

Blake Griffin, NBA star and rumored current beau of the second-youngest Kardashian-Jenner sibling, was targeted by former fiancée Brynn Cameron in a public anti-Valentine's Day stunt.

Cameron filed a palimony lawsuit Wednesday that alleges Jenner of being a homewrecker who destroyed her relationship with Griffin. Further, Cameron accused her ex of humiliating her and her family following his very public displays of affection towards his new squeeze.

Griffin, 28, was first romantically linked to the 22-year-old supermodel last August when the two were spotted enjoying a cozy meal together in West Hollywood. Jenner has since appeared court-side at various Los Angeles Clippers games, cheering her alleged boyfriend on. The two were spotted eating at Nobu and caught venturing out to Long Beach together.

Cameron's filing references Griffin's recent move from the Clippers to the Detroit Pistons, suggesting that breaking promises is just in the basketball player's DNA.

"When Blake Griffin was recently traded ... many speculated that the Los Angeles Clippers had breached their promises to him by dumping the NBA star not long after signing him to a long-term deal. Griffin himself, however, knows very well what breaching promises is all about. After all, Griffin had no problem trading Brynn Cameron, his former fiancée and the mother of his two children, for reality television star Kendall Jenner," reads the suit.

Cameron's suit then goes on to suggest that Griffin cared more about the fame attached to dating Jenner, than about keeping his family together.

It further twists the knife by alleging Griffin has set a bad example for his young daughter, by treating her mother badly.

"Griffin once told the Los Angeles Times he wanted to be an example to his daughter about how she should expect to be treated by men. Sadly, if that is true, she should not expect to be appreciated, recognized for her value, or treated with respect," the lawsuit reads.

Breaking Promises

The basis of Cameron's legal claim against her ex seems to be how she put her career on hold on his explicit instruction. She is described not just as a full-time mother to son Ford, 4, and daughter Finley, 1, but also as a personal assistant, chef, party planner, publicist, and more. Griffin had allegedly agreed to take care of her financially for the rest of her life, in exchange for Cameron giving up her life outside the family home.

The couple's wedding was originally scheduled for July 2017. They had been dating on and off for the better part of a decade. It was postponed just a week ahead of time due to, as the lawsuit alleges, Griffin abandoning his soon-to-be wife and family to shack up with Jenner.

There was also an issue with a prenup, which Cameron reportedly refused to sign. Griffin's ex also alleges that she and their children are broke with nowhere to live, while he continues to rake in millions as a star NBA player. Griffin signed a reported $173 million contract last June.

There has been no public response as of yet from either Griffin or Jenner, but momager Kris Jenner is sure to be calculating her next move. The couple has never publicly confirmed their relationship, with a source telling E! last month that they were just spending time together.
