from www.people.com – Nobody could ever accuse Hugh Hefner of rushing into things.

After an 11-year separation, the Playboy founder, 83, has filed for divorce from his second wife, former Playmate Kimberly Conrad, citing irreconcilable differences, Los Angeles court records show.

The pair were married in July 1989 and separated nine years later, but remained legally wed.

Conrad, 47, is the mother of two of Hefner’s four children, and had for years been supported by him in a home next to the Playboy mansion.

A rep for Hefner wasn’t immediately available for comment. Calls to Conrad weren’t immediately returned.
