Hugh Hefner's secretary/ Playboy mansion den-mother of over 40 years Mary O'Connor has passed away.
"Mary passed away today. We loved her more than words can say." Hef tweeted Sunday. O'Connor--who was featured on the reality series "Girls' Next Door"--was reportedly in her 80s.
Insiders tell TMZ that she was suffering from health issues and that Hef is taking the death "extremely hard." Mary was considered "the rock" of the Playboy mansion and her loss has left an "incredibly sad" mood at the house.
Hugh's ex-girlfriend Kendra Wilkinson also took to Twitter to express her condolences. "RIP Mary O'Connor," she wrote. "She was an amazing person who helped me through so much. But I know she's happy with her boo Captain Bob. :)"
