In an all-new interview with Ok! magazine, John Mayer reveals the reasons behind his split with Jennifer Aniston.

"People have different chemistry, they have different lives," John tells the mag. "It's not about years, it's about going out with somebody, being truthful on the way in, being truthful in the middle and being truthful on the way out. You're either a cheater or you break up and I'm not the first, I'm the second. And that's it. There's no lying, there's no bullsh**."

Despite going separate ways, John, who calls the split "the most normal thing in the world," has nothing but kind words about his now-former flame.

"Jennifer Aniston is the smartest, most sophisticated person I think I've ever met," he added. "She's one of the most lovely people I've ever met in my life."
