PUNK'D YA, KUTCHER!

ASHTON KUTCHER's reps deny reports that pranksters hacked his cell phone and posted his voice-mail messages on the internet — including a salivating babe's salacious, blow-by-blow of her alleged sexual encounter with DEMI MOORE's new hubby! Kutcher's handlers keep crying "hoax" — but the messages sound authentic to me, including three from a "Bruce," who sounds a lot like BRUCE WILLIS, in this reporter's opinion. So, gossip fans, true or false? After listening to a message from a Vegas hotel confirming November 11-12 reservations for "Ashton Kutcher" in the Penthouse Suite, I phoned them. I never uttered Kutcher's name. I recited the confirmation number. "Mr. Kutcher, right?" the clerk said, then quickly stammered, "Wait.. what's the code word...?" HELLO-O!
