Taylor Swift is shaking off ex-boyfriend John Mayer's not-so-nice tweet that he posted on her birthday.
The couple, who dated briefly in 2010, has been very open about their nasty breakup — and John, 39, has obviously still not forgiven Taylor, 27, for penning a song about him.
"Tuesday, December 13 may be the lamest day of the year, conceptually," he wrote in the tweet that was screenshotted by fans before it was deleted.

However, despite the shade, the "Blank Space" singer did get a lot of love from her friends on social media, including BFFs Gigi Hadid, Karlie Kloss and Jaime King.
"Happiest of Birthdays to my ride or die @taylorswift," Karlie wrote on Instagram, along with a Polaroid of the duo. "I feel blessed to count you as my friend, sister and partner in crime. Can't wait to celebrate together very soon."
