Tim Gunn would like to teach a few celebrities some manners.

Tim Gunn wants you to know, that he does not tolerate divas, no matter how famous you are.

Gunn is most adored for his sunny, soft disposition, which makes him very likable amongst the typical motley crew of abrasive reality television stars media whores. But now, Tim is taking aim at a few of fashion, lifestyle, and television’s biggest personalities, and telling everyone just what he thinks of their holier than thou ways.

Tim’s new book, titled, “Gunn’s Golden Rules: Life’s Little Lessons for Making it Work,” scrutinizes Anna Wintour, Isaaac Mizrahi, Padma Lakshmi, Martha Stewart’s daughter Alexis, and even a few of the designers that have graced the Project Runway.

NY Daily News: On calling Mizrahi a spoiled snob in his book, he says, “Oh, please, I was so kind to him. I mean, I wouldn’t have the words to describe some of the more abhorrent behavior. He really is a terrible, terrible, terrible person.”

Please do tell us how you really feel. Terrible, terrible, terrible? That sounds pretty awful. We’re practicality salivating at the thought of the other diva dirt you’ve got to dish, Tim.

The 57 year old Gunn, says that his book blossomed from a simple guide to etiquette, into a guide to good behavior; using your favorite ostentatious celebrity drama queens as an example of exactly how not to act. Tim’s themes include ‘Take the high road,’ you’ll never regret it” and  “Golden Rules” on how to stay cool with “potty-mouthed ruffians.”

Potty-mouthed ruffians, hm? This tabloid world of ours is just full of potty-mouthed ruffians these days, isn’t it, Tim? But, please, don’t try to change their scoundrel ways. What would we have left to write about?

We need the potty-mouthed ruffians, Tim, trust me. We really do.
