Single in the city!

Though she's currently dating NBA star Kris Humphries, when Kim Kardashian filmed her E! reality series, Kourtney and Kim Take New York, last summer, she was single and ready to mingle -- with Kanye West!

On the show's Sunday night premiere, viewers got a glimpse into the 30-year-old's fun, flirty bond with rapper West, 33.

"Kim is single now and she is the most boy crazy girl I've ever seen. She just loves to flirt," sis Kourtney, 31, says after West makes a surprise visit to the pair's DASH boutique in NYC's SoHo neighborhood. (See a clip above)

And after her giggly flirt-fest with West, Kim tells there will be much more of her romantic exploits chronicled on the show.

"I show a lot about my dating life," she tells Us. "Which I've never done before...You'll definitely see a lot more this go round."

Kourtney and Kim Take New York airs Sunday at 10 p.m. (EST) on E!
