Fans are accustomed to seeing Kanye West and Kim Kardashian go just about everywhere together, and their appearances at New York Fashion Week were no different.

When the couple hit Lincoln Center for the Marchesa fashion show this week, onlookers said they were openly flirtatious, flaunting their relationship with PDA for all to see.

A source told Us Weekly that the couple was "all over each other" throughout the fashion show.

"Kanye was twirling Kim's 'fur' fringe jacket," the eyewitness said. "He kept his arm around her the entire time and she kept touching the inside of his leg. They could barely keep their hands off of each other."

West rocked an all-denim look for the fashionable festivities, while Kardashian opted for a silver dress and a fringe jacket.

Though the most eyes in the room were likely on the couple of the moment, other attendees brought equal star wattage, including Vogue editor Anna Wintour, Tyra Banks and Stacy Keibler, who appeared without boyfriend George Clooney.

During the Marchesa showcase, Kardashian opened up about her style evolution since meeting West, who is a fashion maven himself and even designs his own clothing line. West was featured on a recent episode of "Keeping Up With The Kardashians" cleaning out Kim's closet and replacing her clothes with what he thought was more stylish threads.

"It was beyond what you see on a TV show in a couple of clips," Kardashian said. "I liked evolving, I liked growing up a little bit."
