The Keeping Up With The Kardashians star looked sensational as she rocked up to the studio in a mustard-coloured silk vest top that boasted a plunging, lace-adorned neckline and teeny tiny straps.
Proving her fashion credentials, the stunning model - who has walked for Chanel, Dior and Marc Jacobs to name but a few world-famous fashion houses - teamed her barely-there top with a little black skirt that featured cutesy pockets and a fierce chain belt.
Like BFF Gigi Hadid, she managed to pull off a pair of patent boots with a killer block heel that only served to accentuate her lengthy legs. Jealous? Us? Maybe a little...
While on the show with new neighbour Jimmy Kimmel, Kendall lifted the lid on her eye-popping front cover for Vogue's special September issue.
"I'm so happy. I can't even believe I'm here doing this right now, this magazine for this month and this issue. It feels like a dream.
"I shot with some amazing photographers and they make every woman feel so amazing and powerful," Kendall said. "It was an all-Gucci outfit and I felt so sick in it – sick in a good way! I felt awesome."
Even though Kendall wanted the September cover to be a surprise, she admitted that she accidentally let plans for the shoot slip one day...
"The [Vogue magazine shoot] I wanted to keep a secret from everyone," Kendall told Jimmy and his live studio audience.
She went on to say, "My mum was the only one that knew but I slipped up and told Kim! I wanted it to be a surprise, for not only everyone but my family, too. I wanted it to be special."
"You can't blame everyone because there's so many of us," she continued, "but I love having a big family and you always have someone to talk to."
Kendall then went on to talk about her brand spanking new house after giving up her condo.
"It's a lot," Kendall said.
"I'm OCD and the biggest clean freak ever. I'm with my mates when they come over and cleaning, just scrubbing the floors! It's different but it's fun," Kendall finished, "and I wanted space."
