Did on-again girlfriend Katy Perry put him up to this?

John Mayer guest hosted The Late Late Show for three nights this past week, and on Friday he wrapped things up with a monologue that was so awkward it was actually funny.

Mayer plugged the Grammys, which will air Sunday on CBS, and added, "You can see me at the Grammy Awards doing what I do best ... Being avoided by Taylor Swift." Mayer quipped, "that won't make the Internet at all." Sure, but did he come up with this all on his own? We doubt it...

Mayer and Swift briefly dated in 2010, and though the weren't exactly friendly after they split, when Mayer started dating Katy Perry, things seemed to take a turn for the worse. Both Perry and Swift took jabs at one another in interviews and on social media, and when Perry hooked up with DJ Diplo several months ago, he took to Twitter to post a number of nasty things about Swift. Hence why we're wondering if it isn't actually Katy who's causing all the drama...

Mayer is set to perform on Sunday night and Swift is nominated for a handful of awards, including song of the year for "Shake It Off." Wonder if they'll cross paths?
