Turns out Hugh Hefner left his wife, Crystal Harris with an LA Mansion in her name & $5m

After the death of Playboy publisher Hugh Hefner, it was reported that his 31-year-old Crystal Harris will inherit nothing as she was never added to his will and had signed an ironclad prenuptial agreement before their wedding.

It was also reported that his fortune, estimated at $43 million, will be divided among his four children, the University of Southern California and a list of charities.

Turns out Hugh actually cared for Crystal's financial status after his death and made sure he set her up with an LA Mansion and $5M. Read TMZ's report below.

As quickly as Hugh Hefner said "I Do," he rolled out a plan to make sure his wife would be provided for when he dies ... a plan that included a sick pad and MILLIONS.

TMZ obtained the deed to a Hollywood Hills home that is held in trust ... a trust controlled by Crystal Harris. Hef bought the 5,900 square foot house for her back in 2013.

And get this ... sources familiar with Hef's estate plan tell us he also left Crystal $5 million. Based on what we know, the deal is part of a prenup Hef and Crystal signed before they got hitched in 2012.

As for the house ... it's got 4 bedrooms, 5 baths and an infinity pool.
