Kim Kardashian Vs. J. Lo: Watch Diddy Pick The Better Booty

Battle of the booty.

We're sure that Sean "Diddy" Combs has to make tough decisions every single day, but on Tuesday the Bad Boy CEO had to make the most difficult call: Deciding who has the better booty -- Kim Kardashian or Jennfier Lopez?

More specifically, "Access Hollywood" host Billy Bush asked him: Is Kim Kardashian even in the same conversation as J. Lo?

"Noooooo waaaaaaaaaaaay," Diddy answered yesterday when he appeared on the show. "No disrespect to Kanye and Kim but that thing right there, that thing right there is something special."

After plugging his various ventures, the show hosts played Jennifer Lopez and Iggy Azalea's video for "Booty" to get Diddy's reaction and react he did. "Oh my God. I'm so lucky to have that great woman in my history. She is one of the greatest I've ever seen," he gushed about his ex-girlfriend J. Lo.

"It's great, it's a work of art, it's something that will go down in history for real," he said of her backside, before also complimenting Lopez on her talent, drive and determination as well. "She's a great friend of mine, she will always be my friend. That thing is just incredible man."

After the show aired Access Hollywood caught up with J. Lo to get her reaction to Diddy's reaction to her. "As much as he roots for me and as proud as he is of me, and the time we had together, I am just as proud," she responded.
