Today's Page Six has, quite possibly, THE MOST IMPORTANT BLIND ITEM EVER:

• Which Cond Nast honcho is cheating on his wife again? This time it's with a petite blonde with whom he recently had a romantic dinner at Da Umberto. When he saw people he knew, he left and five minutes later she followed him out. They kissed on the street and got in his car and left.

Oh, we simply have to figure this one out. And while we're at it:

• Which pregnant Russian supermodel is showing how uptight American mothers are? She not only continues to drink, she smokes pot.

Same routine as it's always been: Send us your innocent guesses and, at the end of the day, we'll innocently run your innocent insights.
