If you thought the bad breakup between Christie Brinkley and Peter Cook couldn’t get any uglier, think again.

Cook  -- who went through a scandalous divorce with Brinkley in 2008  -- tells ABC News the former Uptown Girl is throwing her family "under the bus" to promote her return to Broadway.

"She can use her celebrity to get the media to say 'He's a bad guy.' You know … I'm not trying to sell tickets to anything. I don't want this press. I'm not interested in it. And there's got to be a better way for her to do it. Go do a charitable act or something, get your name in the paper. But stop throwing your family under the bus,"  Cook, 53, tells Elizabeth Vargas in the interview which was taped Tuesday, but aired Wednesday on Good Morning America.
