The pair broke up almost 7 years ago, but maybe he's not over it…

Taylor Swift is used to throwing shade at her ex’s in the form of one of her ridiculously catchy break-up songs, but now it seems like the tables have turned for the pop-star.

You might remember back in 2009 when Tay was dating Love On The Weekend singer, John Mayer for a few months before the pair swiftly broke up (no, us either).

Well, apparently John isn’t quite over his split with the global superstar – which actually inspired her hit, Dear John – and has taken a swipe at Taylor on her birthday.

While Taylor’s A-list squad were busy showering her with cute messages on social media, John wasn’t so complimentary, branding the Love Story star’s 27th, ‘the lamest day of the year’.

The Gravity singer reportedly tweeted: ‘Tuesday, December 13 may be the lamest day of the year, conceptually.’ Errr ouch.

We can’t actually confirm the brutal dig is about Taylor – because John has gone and deleted the Tweet – but one eagle-eyed fan took a screenshot and posted it, along with the message: ‘Uh. John Mayer just tweeted and deleted this. But thank God for screenshots  #HappyBirthdayTaylorSwift.’


Regardless of whether the Tweet was in fact, a harsh move from her ex, Tay seemed to Shake It Off (sorry) and went on to receive thousands of messages from friends and fans.

BFF, Gigi Hadid left the message: ‘Happy Birthday to you T!! So inspired every day by what an incredible friend you are !!!!!!!! love you & celebrating with u in spirit xx’.

While super-model, Karlie Kloss, posted an adorable snap of the two of them with the caption: ‘Happiest of Birthdays to my ride or die @taylorswift. I feel blessed to count you as my friend, sister and partner in crime. Can’t wait to celebrate together very soon.’

If that’s not #squadgoals, we don’t know what is…
