If You can, try to track down the uncensored version of his "Solitary Man" video. There's a bit (edited out of most showings) of him slipping his hand down his pants (apparently to wank himself). Sigh.
Heard that rumor too.....saw him in October at Burbank-Bob Hope Airport with his entourage waiting for baggage. Filled out his jeans very nicely, but no indication that there is anything unusual in size there.
