John Mayer [1] traded swooning for delivering zingers this week, taking on a three-day stint as host of The Late Late Show on CBS. Although we're used to John addressing his ex Taylor Swift [2] in his music, he decided to make light of their past relationship in his opening monologue [3] on Friday. The topic came up while John was talking about Sunday's Grammy Awards [4]: Taylor is nominated for an award and John is slated to perform with her pal Ed Sheeran. After the joke, Ed appeared on the show for a sketch, interview, and performance with John [5], but he made no mention of Taylor.

This isn't the first time John has garnered headlines by chatting about his former flames — in 2010, the musician described his sex life with his ex Jessica Simpson [6] in an interview with Playboy [7]. Find out what John had to say about Taylor in the two-minute video, above, and don't forget to catch up on the latest viral videos [8].
