P. Diddy is not afraid to speak his mind especially when it comes to Jennifer Lopez's butt!

The rapper recently opened up about his ex-girlfriend, Jennifer Lopez's butt and called it a "piece of art."

Diddy, 45, recently saw JLo's music video for her latest single "Booty" and the rapper is obviously still in awe of his ex's assets.

In fact, Diddy even declared JLo's butt to be much better than that of reality TV star Kim Kardashian, according to Contact Music.

In a recent interview with Access Hollywood Live to promote his upcoming music conference, he said, "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. Show them J, go girl! Go girl!!"

Diddy wasn't shy to elaborate on why he thinks Lopez's behind is unlike that of any other woman's he has ever been with.

"I mean, it's great. It's a work of art. It's something that will go down in history for real it will. But also her talent, her drive, her determination; she will never give up. She's a great friend of mine, always will be my friend and I mean that thing is just incredible man," he explained.

When asked what he thought were the similarities between Kim and Jennifer's butt, Diddy was quick to clarify that Kim's don't even come close to that of Lopez's, Expose noted.

"No way! No way. No disrespect to Kanye West and Kim but that thing right there, that thing right there is something special," he teased.

Meanwhile, earlier this year, Lopez also talked about Diddy and her other ex, Ben Affleck, during an interview, Aceshowbiz reported.

When asked who she would save if she finds Diddy and Affleck floating in the ocean, Lopez joked, "I'd let both mother*ckers drown."

She later on clarified, "That's terrible! I'm just joking! Ben, Puffy, you know I love you. You know that. They know it."
