Bob Mackie's death certificate reveals designer died of 'blunt head trauma and a subarachnoid hemorrhage' after suffering fall… despite his rep citing pneumonia as the cause

New details about Bob Mackie's death have emerged, less than one month after he died at age 87.

The late designer's death certificate, obtained by Us Weekly, has revealed he succumbed to 'blunt head trauma and a subarachnoid hemorrhage' after suffering a fall at a home in Palm Springs.

His cause of death was previously said to be pneumonia, according to a rep who spoke with multiple outlets.

Days before he died on September 14, Mackie fell and sustained an injury while at design director Joseph McFate's residence, according to the death certificate.

It led to the subarachnoid hemorrhage, described as 'bleeding in the area between your brain and the thin tissues that cover and protect it,' per Cleveland Clinic.

The Daily Mail has reached out to a representative for Mackie for comment.

Following the release of his death certificate, a rep for Mackie told Us Weekly, 'For clarification, Mr. Mackie was staying in the guest house at the home of his longtime Design Director, Joe McFate.

'A healthcare professional was with him when he fell.'

The spokesperson added, 'He was also suffering from pneumonia both before and after his hospitalization.'

The renowned fashion extraordinaire's body was cremated on September 17, with his remains spread at sea off the coast of San Diego, the death certificate detailed.

His team confirmed the news of his death with a statement shared on Instagram. 

'It is with a heavy heart that we share the news that Mr. Bob Mackie passed away today,' began the note.

'He lived his 87 years to the fullest, fulfilling his dream of being a Fashion and Costume Designer, which is all he ever wanted to do. His genius and extraordinary designs will live on forever, continuing to bring beauty into this world.'

Mackie worked on the famous sketch for Marilyn Monroe's iconic Happy Birthday, Mr. President dress in 1962, which was designed by Jean Louis. When Monroe requested a skintight, 'naked' look for the gala, Louis instructed Mackie to create the initial sketch.

He was best known, however, for creating over-the-top showgirl dresses for the iconic singer Cher, which won him the nickname Sultan of Sequins.

The Los Angeles native also worked with Carol Burnett, Tina Turner, Barbra Streisand, Diana Ross, Liza Minnelli, Ann-Margret and Bette Midler. 

And he designed gowns for Madonna, Sharon Stone and Julia Louis-Dreyfus, as well as concert costumes for Pink. 

Mackie was a 32-time Emmy nominee as well as a three-time Oscar nominee for his work on the movies Lady Sings the Blues, Funny Lady and Pennies From Heaven.

He also designed costumes for numerous theatrical productions.

His repertoire included work for Lorelei starring Carol Channing, On the Town with Bernadette Peters, and Platinum starring Alexis Smith.

The designer added his magical touch on Moon Over Buffalo and Putting It Together with Burnett.

He also said he loved collaborating with Liza Minnelli on Minnelli Starring Liza. 

His archival pieces are worn today by the likes of Anya Taylor-Joy, Miley Cyrus and Zendaya, the latter who wore a Mackie gown to honor Cher at her 2024 Rock & Roll Hall of Fame induction ceremony.
