Kim Kardashian may have a wedding to plan, but that hasn't stopped her from working -- or guest-judging on Project Runway! Life & Style can reveal that the reality-TV star is set to fly out to New York this week to film with Heidi Klum and company on the hit Lifetime series. "She's going to be a guest judge on the show and is really excited," a source tells Life & Style.

In 2010, Project Runway's very own Tim Gunn took a jab at Kim on The Joy Behar Show. "[Kim's] pretty, but she's a poseur," he said. "I find that when she's static and still, she has an attractiveness. I find that when she's moving, it all goes away from me." As for the rest of the Kardashian family, the style guru, 57, also had harsh words for them. "I just think the Kardashians have an absence of taste, and I don't think that that should be perpetuated," he said in a separate interview.

So, will Kim have her revenge on Tim? We'll have to wait and see...

Kim was previously a guest judge on America's Next Top Model in 2009.
