Why? Note to all P Diddy’s pals (we’re sure he must have one?) – do not drop by to his crib unexpectedly, or you might get an unwelcome glance at his P Dipstick. “I need some advance notice because when I’m at home I’m really likely just to hang totally loose,” says P. “I like to just walk around in my underwear. I get a little embarrassed when people drop by; I’m not really prepared.” Two words Diddy: Dressing. Gown.
