Christie Brinkley Just Wants Peace (VIDEO)

Model and actress Christie Brinkley, 58, came on NBC's "TODAY" show to discuss her upcoming role as Roxy Hart in the Broadway hit "Chicago" -- but left in tears after host Matt Lauer hammered her with questions about her tumultuous divorce.

For the first time in four years since her split with Peter Cook, Brinkley opened up about the vicious turns the divorce has taken. After ending their 10-year marriage, the two have been publicly feuding over child-support claims for their children.

Watch the above video for Brinkley's side of the story.
