WENNWENN

Taylor Swift might seem a perma-smiley star but according to insiders she wasn't exactly Little Miss Sunshine at the Academy of Country Music Awards last month after missing out on five awards on the night and was reportedly "irked" that Mayer was there.

Despite the couple, who dated in 2010, were performing at different venues the We Are Never Ever Getting Back Together singer reportedly insisted that Mayer was moved down the bill so she could perform first.

"She said she had to go on earlier than him," a source told Us Weekly.

But it seems despite getting her own way she was still annoyed at the lothario ex, who has previously attacked her in interviews after she penned break up track Dear John about their romance, the 23 year-old was still annoyed about her ex being around.

"[She] was just really bitter that night especially after she didn't win anything.," the insider explained, "John just being there irked her."

There's certainly no love loss between this former couple. Though they've gone on to date a string of Hollywood babes, they've reserved their most catty comments for each other.

Speaking last year to Rolling Stone magazine about the break up track, Mayer claimed it "made me feel terribl! e," adding it was "a really lousy thing for her to do."

"I never got an email (from Taylor). I never got a phone call," he revealed. "I was really caught off-guard, and it really humiliated me at a time when I'd already been dressed down. I mean, how would you feel if, at the lowest you've ever been, someone kicked you even lower?"

However Swift hit back in an interview with Glamour, calling John's outburst "presumptuous".

"I never disclose who my songs are about," she added.
