John Mayer, licking his wounds after splitting with Jennifer Aniston last week, declared, "This heart didn't come with instructions" on his Twitter Monday.
The talented musician has not been shy in discussing his relationship with Aniston, as he confirmed their breakup last summer to paparazzi lurking outside his New York City gym.
The pair looked to have been back on track as of recently, arm-in-arm with each other at last month's Academy Awards ceremony.
Mayer hasn't lost his sense of humor; he would later note, via Twitter, "My YouTube recommendations would have me believe I only like watching street fights and combustible flatulence." (Photo: WENN)
