Julie Andrews of Mary Poppins and The Sound Of Music fame is one of the most universally beloved celebrities of all time. That’s why it came as a major shock when the former supermodel Janice Dickinson just launched an attack on her.

While appearing on the “Behind the Velvet Rope” podcast this week, Dickinson, 66, claimed that Andrews was rude to her years ago when she only wanted an autograph.

“I once met Julie Andrews at UCLA and she was in this back room and I was politely waiting my turn in line to get a selfie and at least, you know, get an autograph,” Dickinson explained. “And she — she stopped in front of me and she says, ‘I’ve had enough. Thank you.’”

“And I was like, ‘Enough of what?’ she continued. “‘I stood in this line to get your autograph politely.’ She was like, ‘Well, I’m done. I’m tired.’ I was like, ‘F— you, man. How dare you!’ She’s a b****. She hurt my feelings. You can go sound and music elsewhere.”

Dickinson also talked about today’s supermodels, saying that they “do not compare” to her peers from the 1970s and the 1980s.

“The Instagram models get famous and get put into ‘Vogue,’ the Kylie Jenners and the Gigi Hadids and the Bella Hadids. I mean, they are very pretty women, but they’re not supermodels,” she claimed.

“You see them in advertising and Vogue uses them because they have millions and millions and millions of followers,” she added. “Vogue has the subscription of what — 800,000 and Kylie Jenner has got like twenty-five million people following her, something like that. Never on the level of the girls from the seventies and eighties and the nineties, we were fabulous.”

When asked what today’s models are lacking, Dickinson said, “I’m just thinking they’re not, they’re just — they have one look, they don’t really diversify their movements. They just stand there. And get paid millions of dollars. They are not fierce walkers.”

Last month, Andrews spoke out to pay tribute to her Sound Of Music costar Christopher Plummer after he passed away at 91.

“The world has lost a consummate actor today and I have lost a cherished friend,” Andrews told Entertainment Tonight. “I treasure the memories of our work together and all the humor and fun we shared through the years. My heart and condolences go out to his lovely wife Elaine, and his daughter Amanda.”
