John Mayer labels ex Taylor Swift's birthday 'lamest day of year'

The 39-year-old singer posted on Twitter on Tuesday, as Taylor marked her 27th birthday. John quickly deleted the tweet, but not before fans managed to take a screenshot, with the message reading: "Tuesday, December 13 may be the lamest day of the year, conceptually." Despite not mentioning Taylor by name, the tweet was taken by many to be a dig at Taylor.

"Because I didn't deserve it," he told Rolling Stone magazine. "I'm pretty good at taking accountability now, and I never did anything to deserve that. It was a really lousy thing for her to do."

Lyrics on the tune include: "Dear John, I see it all, now it was wrong / Don't you think 19 is too young to be played by your dark twisted games, when I loved you so?"

And as well as feeling "humiliated" by being name-checked in the song, John added to the magazine that he takes issue with it as a songwriter as well.

"I will say as a songwriter that I think it's kind of cheap songwriting," he continued. "I know she's the biggest thing in the world... but I think it's abusing your talent to rub your hands together and go, 'Wait till he gets a load of this!' That's bulls**t."

Taylor later told Glamour magazine that she didn't want to know what John had told Rolling Stone about her tune.

"I know it wasn't good, so I don't want to know," she said. "It's not that I'm this egomaniac and I don't want to hear anything negative... But I've never developed that thick a skin."
