Yikes, Yeezus! Kanye West dissed legendary photographer Annie Leibovitz while speaking at the Cannes Lions Creativity Conference on Tuesday, June 17. His reason? West claimed that Leibovitz canceled her gig as wedding photographer for his nuptials to Kim Kardashian because she was "scared."

"Let me tell you something about that kiss photo that my girl put up," West said (via the New York Post). The rapper, 37, referring to Kardashian's Instagram picture of the newlyweds kissing after being pronounced husband and wife, said it "was pissing my girl off during the honeymoon." He explained: "She was exhausted because we worked on the photo so much because Annie Leibovitz pulled out right before the wedding."

West theorized that the world-famous shutterbug was, "like, scared of the idea of celebrity."

Addressing the crowd in a seminar titled, "Technology, Culture and Consumer Adoption: Learning to Read the Cultural Landscape," the rapper revealed how the couple still wanted the pics to "look like Annie Leibovitz."

Vogue's resident photographer Leibovitz, 64, is revered for her use of bold colors and lighting in beautiful, provocative portraits. The just-married couple spent four days editing the picture during their Ireland honeymoon to achieve her style. "We sat there and worked on that photo for, like, four days because the flowers were off-color," West continued.

"And the fact that the No. 1 most-liked photo has a kind of aesthetic was a win for what the mission is, which is raising the palette," he added. (Kimye's wedding photo on Kardashian's Instagram set a record as the most-liked post ever on the social media platform, garnering more than 2 million likes.) "It was a long time… why did Annie Leibovitz pull out one day before the wedding?" See all the stars in Kim and Kanye’s wedding booth photos here.

Leibovitz, by the way, shot the couple for their talked-about Vogue April 2014 cover. Shortly after its release, Leibovitz joined Twitter and updated her account twice: once, to share her "first official tweet," and the second, to post her "cover shoot for @VogueMagazine, #AnnaWintour with @KanyeWest & @KimKardashian."
