Oh, yes he did!
Comedy legend and Monty Python star John Cleese, 74, dared to throw shade at something dear to Taylor Swift 's heart—her new cat, Olivia Benson. To the singer's face.
The white-haired kitty is a Scottish Fold, a breed with a genetic mutation in which the cartilage of its ears appear folded.
"How did it have the accident?" Cleese asked Swift, 24, as they appeared together onThe Graham Norton Show in London.
"What? What accident?" she said, seemingly confused.
"Is that a proper cat?" he continued. "Or is it damaged? That's the weirdest cat I've ever seen in my life."
Oh, it's on. And it's payback time.
"John Cleese! You CANNOT say that is the weirdest cat you've ever seen in your life!" host Graham Norton said.
A picture of a Cleese's wife Jennifer Wade holding their large long-haired black cat was then shown on screen.
"It's a monster!" Swift, showcasing her trademark astonished look.
"It's an American breed and the reason it's not here tonight is it didn't want to come," Cleese said, turning to a glaring Taylor.
She did warm up to the comedy legend, scooting over to him as fellow guest Kevin Pietersen, South African cricketer, talked about how he is "not a massive fan" of cats, as he is allergic to them. Cleese then said he preferred cats to dogs.
"They're unpredictable and cussed, like women," he said, turning to Swift.
SHADE.
"Ooh, we don't wanna do that," she replied.
Swift introduced the cat, named after Mariska Hargitay's character fromLaw & Order: S.V.U., in June. She also has another Scottish Fold kitty at home, a gray and white one named Meredith Grey, named after Ellen Pompeo's character on Grey's Anatomy.
Swift recently shared on her Instagram page new pics of Olivia Benson, saying, "Last time I let my parents cat-sit, this portrait session/photo shoot happened. There's really no telling what I'll be coming back to this time..."

The cat recently made her debut as a model. She appears in an ad promoting a new addition to Swift's Keds shoes collection.
Swift flew to London to promote her new pop album 1989, which is set for release on Oct. 27. The singer held a secret listening party in the U.K. capital, following similar bashes that have taken place over the past few weeks, including at her home.
On The Graham Norton Show, Swift talked about meeting and sharing her new music with her fans, who she kind of, well, cyber-stalked.
"Well, so, actually, I found them on the Internet," she said. "I would go online, I would look at their Instagram pages or their Tumblr or their Twitter or whatever and just kind of watch them for months and months...and then invited them over and they came."
Norton then joked about some of the fans' reactions to meeting Swift, noting their usage of the word "die." Watch the hilarious segment below (warning: Contains expletives).
Swift's appearance on The Graham Norton Show will air on BBC America on Oct. 18 at 10 p.m. ET.
