The 28-year-old pin-up recently confirmed she'd split from the Playboy boss, 82, and he admits the break-up has left him devastated.

He tells Us Weekly magazine, "I had planned to spend the rest of my life with Holly. I was roadkill a couple of weeks ago."

And Hefner suggests the couple's failed efforts to become parents may have led to the split.

He tells E! online, "With my sperm count, it's not possible.

"I was willing, but it was not possible… She'd like to be married and have children, but it's not in the cards here for me."
