Press-hungry vodka magnate Martin Silver is picking a fight with Sean Combs after reading on Page Six how Diddy yelled, “If you’re not drinking Ciroc, you’re drinking pee pee,” to partygoers at Greenhouse. Silver — whose Star Industries produces Georgi, Major ska, Argent and Alexi — will deliver a toilet bowl full of Ciroc to Combs’ corporate offices today and hold a press conference in Times Square demanding an apology from him. “I take umbrage,” said Silver. A rep for Combs had no comment.
