Jessica Simpson appeared on David Letterman last night where she talked about Tony Romo, and the infamous ‘sexual napalm‘ revelation by John Mayer.

I found it interesting that she admitted her and Tony Romo are still friends yet when David asked her why they broke up she said she didn’t know and he would have to ask Tony.  So if you are still friends wouldn’t that come up in conversation or have been discussed?
