Brynn Cameron, the mother of Blake Griffin's kids, has filed a lawsuit against the Pistons star that claims he left her and their children for Kendall Jenner. According to TMZ, the lawsuit says Griffin stepped out on his fiancee after "cruelly embarrassing his family with his public fawning over Kendall Jenner."

The former couple, who had dated on and off for eight years, have both a son and daughter together. They were also engaged (hence the fiancee line above) but that wedding was broken off this past summer after Griffin became taken with Jenner. According to Cameron, that break-up came a week before their wedding, and was the result of her refusing to sign a prenuptial agreement that she says she didn't sign because it violated a pact they made in 2013.

As TMZ notes, the lawsuit also invokes Griffin's recent trade to Detroit to talk about what it's like to have your trust violated (I think). "Griffin himself, however, knows very well what breaching promises is all about," it says. "After all, Griffin had no problem trading Brynn Cameron, his former fiancee, and the mother of his two children, for reality television star Kendall Jenner."

The lawsuit, which was filed on Wednesday, says that Griffin repeatedly told Cameron he'd support her while telling her to quit her jobs in sports marketing and interior design. The suit also includes a pair of love letters from Griffin that you can read here if you wish.

Finally, the litigation also talks about how Cameron helped counsel Griffin through a feud with ex-teammate Chris Paul as the two apparently battled for the Clippers' locker room. As it's written in the actual lawsuit "[Cameron] strengthened Griffin's bond with his teammates and allowed the organization to see a different side of his personality rather than the hard-partying man-child Griffin had been prior to their cohabitation."

Cameron goes on to say that Griffin's decision to date Jenner left her and their kids in poor financial shape, saying, "While Griffin is continuing to earn millions from his NBA and endorsement deals, Cameron and their children are homeless and cash-strapped. In Griffin's absence, Cameron's brother has had to provide Cameron and the children with financial support."

The legal proceeding doesn't ask for a specific amount, but TMZ says it's definitely seven-plus figures.
