John Mayer Sings for Seth Meyers After Splitting from Katy Perry

John Mayer performs a song during the first week of Late Night with Seth Meyers on Thursday (February 27) at NBC Studios in New York City.

Also making an appearance on the show that evening was Girls star Lena Dunham.

It was reported earlier this week that John and his on-and-off girlfriend Katy Perry have split once again. This is his first official appearance since the split, but he was just a musical guest on the show so there probably wasn’t a chance to ask him about it.
