This morning John Mayer debuted a new song: a cover of Beyoncé's hit "XO," and it's just as soulful and romantic as you would imagine.
The song -- which features Mayer's signature acoustic guitar and harmonica --was not publicized and seems to have been teased by Mayer two weeks ago when the rocker took to Instagram with, "I love you like XO."
Although Mayer previously performed his version of "XO" on tour in Adelaide, Australia last month, this new version will be released via iTunes next week.
