Hugh Hefner's extended family and friends want to hold a memorial to remember him.

The Playboy magazine founder passed away earlier this week at the age of 91 and his Hollywood pals are reportedly planning a little service at the Playboy mansion so they can have a chance to say goodbye to him after he was laid to rest in an intimate service over the weekend.

A source told ''The funeral on Saturday was so top-secret and his friends did not get to say goodbye. So they are gathering this week to have their own sort of memorial service. His extended family and friends are hoping to have the memorial at the Playboy mansion, but nothing is set in stone yet.''

Hugh's widow Crystal recently broke her silence on her husband's death, where she spoke of his ''kind and humble soul''.

In a statement, she said: ''I haven't been able to bring myself to write most people back to thank them for their condolences. I am heartbroken. I am still in disbelief.

''He was an American hero. A pioneer. A kind and humble soul who opened up his life and home to the world. I felt how much he loved me. I loved him so much.

''I am so grateful. He gave me life. He gave me direction. He taught me kindness. I will feel eternally grateful to have been by his side, holding his hand, and telling him how much I love him.''

Hugh was laid to rest on Saturday at Los Angeles' Westwood Village Memorial Park. He has been buried next to Marilyn Monroe, a space which he is reported to have purchased for $75,000 in 1992.

He also has several friends buried there, including jazz musician Buddy Rich and Canadian Playboy Playmate, Dorothy Stratten, who was murdered in 1989.
