NEW YORK (EY): John Mayer has sued a man for selling him fake Rolexes. The ‘Who You Love’ singer spent a total of $5 million on what he believed to be a collection of authentic luxury watches from dealer Robert Maron - a friend of Charlie Sheen - back in 2007 but was shocked to find one of the timepieces was a replica when he sent it off for repairs three years later. According to TMZ, Mayer returned the watch and was given credit to buy another but now wants a refund for $656,000 he spent on seven other watches.
