Diddy gets personal on his new album, Press Play, with songs inspired by girlfriend Kim Porter and his famous ex, Jennifer Lopez.

"It's probably my most personal record," Diddy, 35, said Friday after announcing the launch of Best Buy's new digital music store in New York City. "On a lot of the other records, to be honest, I didn't do a whole lot of writing. On this one, I did a lot. And I exposed myself with everybody's most sensitive subject, and that's the subject of love."

And yes, that includes his relationship with Lopez, whom he dated for two years before they split in 2001. "I used every experience," he said. "She was one of my girlfriends, and the most highly publicized one. But I've been blessed to go out with a couple of great women, and she was one of the great ones."

Do he and Lopez still talk? "Yeah. We're ex-boyfriend and girlfriend. And that's cool. It's a positive thing. But my focus right now – when I'm with a woman, I'm focused on that woman."

That woman is Kim Porter, with whom he's expecting twin girls. "The relationship that gave me the most inspiration was the relationship with Kim," Diddy said. "(It's) my most long-term relationship. It's had a lot of ups and downs, and it made for a lot of great songs."

And when their twins are born, will he raise them differently than he has his two sons, Justin, 12, and Christian, 8? "I don't know yet," he said. "We're just praying."
