The busty blonde claims Ultimate Fighting Championship star Tito Ortiz reneged on a deal to have her name added to the title deed of the Huntington Beach pad they shared before their 2013 split.

Jameson, who reportedly provided the bulk of the down payment for the property, alleges she agreed to have Ortiz listed as the main owner as long as she received half of the financial interests, according to legal papers obtained by the Orange County Register.

Ortiz has yet to respond to the lawsuit. He still lives in the property with the former couple's six-year-old twin boys.
