Playboy boss HUGH HEFNER has filed legal papers to put an end to his marriage to KIMBERLY CONRAD – 11 years after the couple split.

The ageing lothario has romanced a bevy of beauties since he and former Playboy Playmate Conrad parted ways in 1998, but he has only recently taken action to legally dissolve the union.

According to TMZ.com, Hefner filed documents in Los Angeles County Superior Court last Friday (04Sep09), requesting a judge set spousal support at $20,000 (£13,330) per month.

Hefner claims he has paid Conrad almost $12 million (£6 million) since 1998.

Relations between Hefner and his ex have been strained in recent months after the media mogul sold the house next door to his famous Playboy Mansion in Beverly Hills – where his two sons with Conrad, Marston, 19, and Cooper, 17, had been living.

Last month (Aug09), Conrad, who wed Hefner in 1989, took legal action against the 83 year old, claiming he has failed to honour their pre-nuptial agreement and allegedly owes her more than $5 million (£3.3 million).
