Musician John Mayer has split from his manager Michael McDonald after 13 years together. No reason for the break has been given, but McDonald confirmed the news in a statement that reads, "After 13 years, John and I are parting ways. It's been a magnificent journey, which began before his debut album, and along the way has included seven Grammy awards, years of massively successful tours around the world, and over 20 million albums sold. I hold John's talent in the highest regard and wish him nothing but the best." McDonald, who also manages other artists such as Passion Pit, St. Lucia, and Ray LaMontagne, finalised the split on Tuesday (03Dec13). Mayer is currently on the second leg of his John Mayer Live In Concert tour in North America.
