The 23-year-old actress starred as a guest judge on the sixth season of Lifetime’s Project Runway and has been lauded by the program’s consultant.

“I was surprised and pleased by how extremely knowledgeable about fashion and articulate Lindsay Lohan was,” he said. “She’s very young and can be portrayed in ways that aren’t all together flattering, and she was a true statesperson and really weighed in on the designers and what they were doing exceptionally well. And it was really a thrill to have her.”

“In his case, everything is too big… If you want to dress to feel as though you never got out of bed, then don’t get out of bed,” Gunn said speaking to Us Weekly.

Gunn added that he is “accepting” of Kate’s famous circa 1987 haircut, explaining: “If that’s the way she wants to present herself then she’s doing a good job.”

Tim recently revealed that he has a “celebrity crush” on the host of CNN’s Anderson Cooper 360° — who has always been cryptic when it comes to addressing questions regarding his sexuality. Although the potential couple has yet to enjoy a first date, Tim admits the two are friends, who e-mail one another often.

“He’s fabulous,” Tim squeals. “I love his brain, looks, and style,” the fashionisto added with a smile. “We’ve actually been trying to have lunch for a year and a half,” he explains. “Both of us are so busy that we haven’t been successful doing it, but we exchange e-mails.”

Project Runway’s Tim Gunn is teaming up with PETA to urge noted designers to just say “no” to fur.

Tim filmed a personal video for designers Giorgio Armani and Donna Karan to ask them to stop using rabbit fur in their collections.

“Any designer in the fashion industry who does not want to watch the PETA video and see exactly what happens to animals and how they’re treated and how the product that they use comes to the marketplace, I believe, is egregiously irresponsible.”

Why were Armani and D.K. singled out?

Well, according to PETA spokesperson Michael McGraw “they have both made pledges to be fur-free, but have gone back on their word when it comes to rabbits, as if rabbits aren’t fur-bearing animals.”

In response to the claims, an Armani rep says, “Despite the fact that we have previously sold products made from animal fur, the Armani Group has now decided to renounce making such items with the exception of those in rabbit fur, the by-product of an animal that is a staple source of food… We must stress that PETA is exploiting our name to stir up public opinion without acknowledging that we actually include very few fur items in our collections, while certain competitors of ours base much of their business on furs.”

A Donna Karan spokesperson is taking a similar stances: “There is no fur in any of our lines for Fall 2009, and we currently have no plans to use fur.”
