It continues to claim that she ran almost every aspect of the couple's lives: "Cameron was not just the mother of Griffin's children and their caregiver, she was also a constant support for Griffin - his personal assistant, meal planner, scheduler, stylist, publicist, party planner, nurse, nutritionist, branding expert, therapist, cheerleader, basketball and fitness consultant and more".
The former couple, who had been off and on for the past eight years, called off their wedding last year and Griffin moved on with model and reality TV star Jenner, 22.
Brynn filed a palimony suit against Blake, and she claimed that he is 'cruelly embarrassing his family with his public fawning over [Kendall] Jenner, ' he told her he 'had no intention of continuing to live with her'.
In the lawsuit, the blonde claims that she and the 28-year-old made an oral agreement in 2013 that she would quit her job and focus on raising their two children so that he could focus on getting a big National Basketball Association contract.
After the postponement, Cameron says Griffin "immediately embarked on a high-profile affair with Jenner".
"Griffin cared more about the glamour of dating a Hollywood celebrity than the day-to-day responsibilities of being a father and family man", the suit added.
Soon after the sessions, Cameron discovered through media reports that Griffin was dating Jenner.More news: Amazon Echo devices now available for offline purchase in India

Cameron is saying the Griffin has refused to provide financial support for her or their kids and has "abandoned" them.
The suit claims that Cameron and their two kids are homeless and strapped for cash relying on her brother for money.
But things came crashing down, Cameron claims, after they postponed their summer 2017 wedding, instead choosing to go to couple's therapy.
Blake's ex is reportedly looking for millions in the suit, but an exact number is not known at this time.
Reports emerged in August a year ago that Kendall was dating the basketballer, after they were spotted at dinner and Kendall was then photographed at many a game cheering on her lad.
It was reported in December that Griffin's romance with Jenner had sparked a nasty custody battle.
The two began dating through Griffin's first year in the National Basketball Association and Cameron claims she was a source of support for him after he injured himself.
