Taylor Swift Grammy Drama: Award-Winning Singer Eludes Katy Perry, John Mayer; Forgives Kanye West And Diplo

As she has been assigned to be the presenter for Best New Artist Award in the Grammys, Taylor Swift also get to meet past adversaries in the occasion-some she ignored and some she ended the feud with.

The Grammys seating arrangement is meant to separate Taylor and Katy Perry as Katy who is seated next to Prince while the Blank Space singer is seated next to Haim, Hollywood Life said.

A source from the tabloid said that the two pop stars continued to avoid each other during the rest of the show.

"Word was that Taylor Swift was meant to show up, and Katy left before any of that could happen. Taylor didn't show because rumors were that she knew Katy was there, and Katy left thinking Taylor was going to show, so they definitely made an effort to avoid each other," the source said.

Months ago, Katy is alleged to have to have convinced Swift's back-up dancers to leave the group and join her on the Prism tour.

The diss heightened when the 30-year old singer intentionally let her back-up dancers wear one of Taylor's familiar polka dot swimsuits as costume on stage during her half-time Superbowl performance, a separate report from Hollywood Life said.

As for his ex, John Mayer, the 26-year old singer also tried to shake her past off from the rocker as she had also avoided seeing him during the occasion.

This followed days after the rocker John Mayer had also thrown shade on her while hosting the "Late Late Show on February 6, Aceshowbiz reported.

"You can see me at the Grammys doing what I do best, being avoided by Taylor Swift. That won't make the Internet at all," Mayer said jokingly.

Meanwhile, the singer ended the misunderstanding with Kanye West and music producer Diplo. The NY Daily News said.

Swift and Kanye are seen together with warm, friendly smiles in front of the camera.

Music producer Diplo who had a feud with the singer last November, with a few fowl remarks against the singer, is also seen partying with her. The producer shared the picture on his Instagram saying, "Then this happened @taylorswift vs taylor spliff#grammys2015."
