APPARENTLY UNAWARE THEY'RE THE MODERN GODS: If Jessica Simpson ever runs for president - not such an unlikely prospect, no smarts and a pushy father is exactly the same profile as the present incumbent - she's going to find her path made tricky by the catcalling of New York firefighters. Simpsons's birthday party at Butter, some sort of New York nitespot, was broken up by the fire bobbies due to overcrowding. The assembled celebs were not amused - "go fight a real fire" shouted one, wittily. It almost makes you wonder why anyone would bother ensuring that Simpson and her guest list - Usher, Sky Nellor, Naomi Campbell - would be able to evacuate safely in the event of a fire. We'd not be talking much of a loss.
