DENNIS RODMAN - RODMAN SURPRISED HE COULDN'T IMPREGNATE MADONNA

LATEST: Basketball bad boy-turned-socialite DENNIS RODMAN is still surprised he didn't father a child with ex-girlfriend MADONNA because she went out of her way to get pregnant when they dated.

In his new autobiography I SHOULD BE DEAD BY NOW, Rodman claims Madonna once flew from Las Vegas, Nevada to New York in an unsuccessful attempt to conceive the former Chicago Bulls star's child during their romance in the early 1990s.

And Rodman still can't understand why their fling didn't produce a baby.

He says, "She just would do the weirdest things to make sure she was going to get impregnated by Dennis Rodman. It didn't work. I'm pretty potent. I'm surprised."

Madonna later conceived her daughter LOURDES with dancer CARLOS LEON and later gave birth to husband GUY RITCHIE's son ROCCO.
