John Mayer Rumors

Sam Cassell has something in common with John Mayer — they both bought expensive watches from the same guy … a guy accused of selling FAKES … and now the former NBA star tells TMZ Sports he’s bringing in experts to see if he got ripped off. We broke the story … Mayer is suing Charlie Sheen’s BFF Robert Maron — claiming he bought $5 million worth of Rolex watches from the guy … some of which turned out NOT to be 100% authentic. Cassell tells TMZ Sports he also bought a watch from Maron — “It’s an A. Lange & Sohne. It cost me a nice piece of change.”
