It's just me and my bad bitch
So you can say I'm on my Brad Pitt

from Rihanna (Ft. Kanye West) – Diamonds Remix Lyrics on Rap Genius

Meaning

Kanye and Kim’s combined star power and blossoming romance has been frequently making front pages in the tabloids. Just like Brad Pitt and Angelina Jolie have been since they got together in 2004.

Also to be noted…Kanye did a song entitled “Perfect Bitch” as a dedication for Kim Kardashian…the song didn’t go over well with her since she didn’t like being called a bitch causing Kanye to do some self-reflecting on Twitter

The fact he fades out the word in this song should not be overlooked

One must not overlook the obvious reference to Mr. and Ms. Smith, where Angelina Jolie plays the villainous (aka bad) wife of Brad Pitt.

May also be a reference to this
