'Absolutely no shade': John Mayer goes into damage control after branding Taylor Swift's birthday the 'lamest day of the year' 

John Mayer has insisted he meant 'no shade' at ex-girlfriend Taylor Swift, after labelling her birthday the 'lamest day of the year.' 

After deleting his original tweet, which appeared to take a swipe at the Shake It Off birthday-girl, John defended himself, writing: 'NOPE. No. Nuh-uh. People I am 39. I am deleting those tweets. Come right at me for doing so, Absolutely no shade'.

John and Taylor dated briefly from November 2009 to February 2010, with their acrimonious split inspiring her hit-song, Dear John.
