Andy Cohen and John Mayer love each other. On Wednesday’s episode of SiriusXM’s “The Howard Stern Show,” Cohen said: “I am in love with John Mayer. We are in love with each other.” Cohen and Mayer have been longtime friends. Stern commented that Mayer was probably the most-mentioned person in Cohen’s new book, “The Daddy Diaries: The Year I Grew Up,” pointing out that the two have even been on camping trips together. “Swear on your children’s lives that there has never been anything sexual between you and John Mayer,” Stern said. “Yes. I do. I swear,” Cohen said, swearing on the lives of his children.
