Professional opinion giver Tim Gunn has been making the press rounds to promote his new book, 'Gunn's Golden Rules,' and he hasn't been shy about sharing his thoughts on a variety of stars. The latest celebs to find themselves in Gunn's crosshairs: Lindsay Lohan, Tom Cruise, Katie Homes and 'Real Housewife of D.C.' Michaele Salahi.

In an interview with Access Hollywood Live, Gunn didn't exactly have kind words for White House party crashers Michaele and Tareq Salahi -- who were waiting to be interviewed via satellite and heard the whole thing. "I don't mind if the Salahis hear this -- I believe that they are sociopaths," he said. "They believe their own lies. When you're dealing with a sociopath, you can't reason. You can't deal with logic. ... They do believe their own lies in my view."

Oh, and he also doesn't believe Michaele suffers from multiple sclerosis, as she recently revealed. "I would never wish MS upon anyone. And if in fact Michaele has MS, I feel very bad for her," Gunn said. "I have a very dear friend who has MS. I find it curious that the story is coming out now, though. I would want a doctor's note."
