Mary O'Connor, considered to be a confidante to publisher Hugh Hefner for 40 years, was a beloved figure in the Playboy family.
Mary O'Connor, Hugh Hefner's longtime secretary, passed away over the weekend.
"Mary passed away today,” Hefner wrote Sunday night on his Twitter account. “We loved her more than words could say."
When Hefner was engaged to Playmate Crystal Harris in 2010, Harris, now 26, had called off the wedding just five days before the planned 2011 wedding. Harris and Hefner reconciled in 2012, marrying this past New Year's Eve.
"It's Mary O'Conner [sic] that brought Crystal Harris back," Hefner tweeted at the time of his and Harris' reconciliation. "Crystal was miserable & said so. Mary told Crystal to write & tell me, which she did."
O'Connor, considered a confidante to Hefner for 40 years, was also known for counseling dozens of aspiring 'bunnies' who lived at Hefner’s Los Angeles mansion. She was also featured in the 2005 reality TV series "The Girls Next Door," which focused on Hefner's girlfriends who lived with him at the mansion.
Former girlfriend Holly Madison also took to Twitter, re-tweeting an image of a rainbow along with the words, "Rest In Peace Mary!"
Another former girlfriend and current television personality, Kendra Wilkinson, tweeted, "RIP Mary O'Connor. She was an amazing person who helped me through so much. But I know she's happy with her boo Captain Bob. :)"
Actress Jenny McCarthy, who began her career as a Playboy model, later added, "R.I.P. Mary O Connor from Playboy She was Hef's secretary for 50 years. She was our 'den mom' and angel in the house. She will be missed."
According to TMZ, O'Connor, in her 80s, had been recently struggling with health issues.
