Paris has still been filming for her BFF reality show. A friend close to the PCM staff recently saw Paris being followed by cameras through LAX airport at the beginning of July.
"The show is going to be about her searching for a new best friend," a source tells Usmagazine.com. "Paris is tired of the haters and she's looking for someone new. She's looking for someone new and cool who she can trust."
Her show, expected to be picked up by either MTV or VH1 – will be her second foray in reality television. Remember The Simple Life with her friend Nicole Richie?
The new show is "going to be full of good chick drama and you will see a side of Paris not seen on Simple Life," the source tells Us.
