Whether they're BFFs or frenemies, there's never a dull moment for Paris Hilton and Nicole Richie. Unless of course you watched The Simple Life, but we digress...

The latest rift is that Paris and Benji Madden moving in next door to Nicole and her baby daddy (Benji's twin bro, Joel) has transformed their suburban Glendale serenity into tiresome gossip-hound squalor. A pal of Richie's tells Page Six:

"Nicole moved out there to get away from the paparazzi, but when Paris calls them, they come to her quiet street and disrupt everything. She's getting a little fed up."

Trouble in paradise? Sure, but that's just par for the course. These two are always having some kind of episode. Were just happy it's not another episode of their show.
