Hugh Hefner said he waited more than 10 years to complete his divorce "because of the children."
"I stayed married not because it was a marriage — the marriage ended in 1998," he said. "I stayed because she wanted me to."
But now his twin boys are turning 18, so the 83-year-old Playboy magazine founder says, "Now is the time."
On Friday, Hefner filed for divorce from former Playmate of the Year Kimberly Conrad Hefner. The couple married in 1989 and were legally separated in 1998.
