Playboy mogul Hugh Hefner has finally filed for divorce after an 11-year separation from his second wife.

The 83-year-old remained legally married to former Playmate Kimberly Conrad, whom he wed in 1989 and separated nine years later.

Hefner, who is who is presently dating Playmates Crystal Harris, 23, and twins Karissa and Kristina Shannon, 19, has finally turned to court citing irreconcilable differences, Los Angeles court records said.

“I would”ve been happy to divorce her when we separated, but she wanted to remain married for our boys,” People magazine quoted him as saying.

Hillel Chodos, a lawyer for Conrad, 47, the mother of two of Hefner”s four children, said: “Mr. Hefner”s divorce filing speak for itself, and we”ll respond in due course.”
