Calvin Klein is seeking substance-abuse help after his mid-game courtside discussion with Latrell Sprewell. Kal Ruttenstein, the fashion director of Bloomingdale's, hyperventilates, "Something like this creates a lot of damage for a designer because people don't respect that kind of behavior...I see damage because Calvin opened his first in-store boutique at Bloomingdale's and customers know him from personal appearances. I see damage on all levels, from underwear to ready-to-wear."

During Monday night's Knicks game, Calvin Klein apparently walked up to Latrell Sprewell as Sprewell was getting ready to inbound the ball and struck up a conversation with him before being escorted away by security. A number of possible explanations here:
1. Klein has gone completely batshit. (A reader points out that he once called Joan Rivers a "nasty cunt" to her face, but I'm not sure that's indicative of mental instability, as many of us wouldat the very leastbe tempted to do the same thing after a few reasonably strong cocktails.)
2. Klein has decided that being a mere cokehead isn't enough, and added a few hallucinogens to his narcotic repertoire.
3. His Brazilian rent boy dared him to do it. (You know, if he had a Brazilian rent boy. Not that we're suggesting...)
