TMZ received a statement from Playboy founder Hugh Hefner:

“I am very saddened to learn about Anna Nicole’s passing. She was a dear friend who meant a great deal to the Playboy family and to me personally. My thoughts and prayers are with her friends and loved ones during this difficult time.”

Hefner famously purchased the Westwood crypt where Marilyn Monroe is entombed. Monroe was the first Playboy Playmate. Anna was Playmate of the Year in 1993.
