Overexposure is to blame for the cancellation.

“We felt like the real life drama of their lives overshadowed anything happening on the show,” says the insider. “Viewers would see Paris all day long on the news about her going to jail, so they didn’t care about seeing her camping with kids. It just was too played out.”

The source adds that Nicole Richie became increasingly difficult to work with last season.

“Paris carried the show. She was the one willing to do anything,” says the source. “Nicole was the diva.”
