Remember when Paris Hilton had her Sidekick hacked into and all those celebrity phone numbers and emails were out there for the stalkers to see? Well no one really paid much mind to the fact that Paris had the number of San Francisco mayor Gavin Newsom in there. Except me. I tried to holler about it, but no one cared. Shortly after that incident, Newsom and his wife, cable TV news talking head Kimberly Guilfoyle, split. Well we have an excellent, inside Bay Area source who has confirmed exactly what we thought. That Paris Hilton and Mayor Newsom had a little fling. Hardly shocking or that titilating, considering he's a a playboy and she's a Penthouse pet. But still.
