According to court documents, Laurence Hallier, a real estate tycoon who dated Anderson back in 2006, promised her a condominium in a new Las Vegas development he invested in. In return she would help publicise the luxury building - The Panorama Towers.

Anderson claimed he told her that if the development was delayed in anyway she would be given $1million in cash and when the project fell behind, she never received her payment. Anderson filed a federal lawsuit this week with the Los Angeles Superior Court asking for the $1 million fee to be paid.

The couple are said to have dated on and off for several years, finally ending their fling last year.
