Porny Pete -- Christie Jacked Son's Trip!

And you thought the radioactive Christie Brinkley-Peter Cook divorce was over. Not quite.

Cook's lawyer told us he filed contempt of court papers yesterday against Christie, claiming she didn't hand over son Jack's passport back in November, thereby preventing him from being able to take a school trip to Egypt. They claim she broke an agreement to hand over the passport on or before Nov. 19.

Two things here: Peter Cook calling out anyone for being a bad parent, and ... who takes a field trip to Egypt?
