West, 35, who ha his own DW Kanye West fashion line, wore a denim shirt and denim jeans to the show, while Kardashian, 31, wore a white dress with a fringe top. The PDA-friendly couple sat front row between Tyra Banks and George Clooney's girlfriend Stacy Keibler. Stars Michelle Trachtenberg, Rachel Roy, Sarah Hyland and Anna Wintour also attended the show.

"Kanye was twirling Kim's 'fur' fringe jacket," an eyewitness says. "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."

Last week, Kardashian visited The View and opened up about her relationship with West to Barbara Walters. "Technically I'm still married," Kardashian said of her still-pending divorce from NBA star Kris Humphries, 27. "Anything I'd be in now would be a permanent relationship."

And when Walters asked if her relationship with West is permanent, Kim replied, "I hope so. I believe so."

She also hopes to have babies!

"At the space that I am in life now, kids are definitely something I want," the Keeping Up With the Kardashians star said. "I think I wanted that before. I think I fell in love so quickly and wanted that to be my life so badly but I just didn't take the time to find someone."
