Prince Harry Sniffed Princess Diana's Perfume 'Like A Tab Of LSD'

Prince Harry opened up about the aftermath of Princess Diana's tragic death and revealed that his mother's "favorite" perfume helped him process his grief.

The 38-year-old Duke of Sussex's recently released memoir, "Spare," divulged the details of how he coped with the death of his beloved mother, having to attend therapy sessions during his younger years.

Prince Harry recalled that he even brought Princess Diana's perfume to a therapy session and sniffed it as a way of reminiscing memories that reminded him of the familiar scent.

"At the start of our session, I lifted the lid, [and] took a deep sniff. Like a tab of LSD," Prince Harry wrote, according to an excerpt obtained by Page Six.

He continued, "I read somewhere that smell is our oldest sense, and that fitted with what I experienced [at] that moment, images rising from what felt like the most primal part of my brain."

The outlet noted that the perfume in question might be First by Van Cleef & Arpels, a scent that featured key notes of hyacinth, rose, jasmine, amber and sandalwood, which was one of the then-Princess of Wales's most used fragrances.

Prince Harry also mentioned his father King Charles III's cologne in th book, saying he remembered smelling that fragrance the night before his mother died over 25 years ago in a fatal car crash in Paris, France.

"He was always sniffing things. Food, roses, our hair. He must've been a bloodhound in another life," he wrote, referring to the then-Prince Charles, adding that "maybe he took all those long sniffs because it was hard to smell anything over his personal scent. Eau Sauvage."

"Flowery, with a hint of something harsh, like pepper or gunpowder, it was made in Paris. Said so on the bottle. Which made me think of Mummy," he said.

As part of the promotions for "Spare," Prince Harry was interviewed by multiple media outlets after the excerpts leaked online before the book hit shelves on Tuesday.

In an interview with CBS' "60 Minutes" with host Anderson Cooper, the Archewell Foundation co-founder went into detail about the death of his mother, which happened when he was only 12 years old, according to the Independent.

During the interview, he revealed that he initially thought the late Princess Diana "faked" her death to escape the British press.

The Duke of Sussex said that he believed "for a long time" that his mother just "decided to disappear for a time" but would call her two sons, Harry, and Prince William, to "come and join" her wherever she was.

"I just refused to accept that she was gone. Part of, she would never do this to us but also part of, maybe this is all part of a plan," he said, adding that his older brother, the 40-year-old Prince of Wales had "similar thoughts."

While speaking with "Good Morning America" co-anchor Michael Strahan, Prince Harry clarified that the belief that his mother went into "hiding" was a "defense mechanism" since he refused to accept the tragedy at such a young age.
