The `Coming Home` rapper - who already has five children, Justin, 17, Christian, 12, Chance, four, and four-year-old twins D`Lila Star and Jessie James, by three different women and is an informal stepfather to another child, Quincy Jones Brown, the son of his on/off girlfriend Kimberly Porter - admits the news the couple are expecting their fourth child together has made him broody.
Diddy - who is close friends with soccer player David - said: "I last saw Beckham a couple months ago. We are both proud fathers. That`s what our friendship is about, not being stars or artists.
"We ask how are kids are doing. I`m so happy he`s got another on the way. I hope he has as many as me. I want more."
Although he is currently single, the 41-year-old music mogul - who has never married and has dated a number of beautiful women including Jennifer Lopez - hasn`t given up on the idea of finding true love and admits he is slightly envious of fellow rapper Jay-Z`s happy marriage to Beyonce Knowles.
He said in an interview with the Daily Mirror newspaper: "I`d love to have what Jay and Beyonce have. My ideal woman has to have intellect and soul. I don`t woo them with flowers, I need to know they like me for real."
Last month, the Diddy-Dirty Money star admitted his children`s mothers - his high school sweetheart Misa Hylton-Brim, Kimberly and Sarah Chapman - "deserved" to have married him.
He said: "Life isn`t something you can predict. Every woman that I was with, that I had a child with, they did deserve for me to marry them. But there`s things going on in my life ... I`m not gonna say it`s all the way me, but I`ll take responsibility as a man."
