LATEST: Christie Brinkley's daughter with rocker Billy Joel is proud of her model mother for making her divorce battle with Peter Cook public.
Brinkley, 54, is due to fight estranged husband Cook in a New York court on Wednesday (02Jul08), when their divorce goes to trial.
She filed for a legal separation in 2006, over his alleged affair with a then-18-year-old assistant.
According to reports, among Brinkley's divorce allegations are claims that Cook trawled the internet for women and porn.
The beauty, who has kids Jack, 12, and Sailor, nine with Cook, has been criticised by her ex and their children's guardian Theresa Mari for making their divorce proceedings open to the press - but Alexa Ray Joel, 22, has praised her mum's efforts.
She tells People magazine, "She's standing up for herself. I think that is admirable. There's such overwhelming support for her."
