Taylor Swift brings out Avril Lavigne on stage for a special duet! Another day, another surprise performance on swifts 1989 world tour… And this my friends is ANYTHING but complicated. Avril Lavigne stepped onto the stage to perform her hit song ‘Complicated’ along side Taylor in San Diego… I’m actually starting to think that the possibilities are completely ENDLESS when it comes to guests appearing on this 1989 WORLD TOUR…Avril posted not just one but THREE photos on Instagram to share her excitement after the performance including this one saying QUOTE: "Such a Pleasure to perform "Complicated" tonight with @taylorswift on her #1989 world tour! She ROCKS!" And JUST in case you missed the epic moment don’t you worry because I’ve got you covered! I can’t even; I’d be lying if I tried to tell you that this wasn’t my jam back in the DAY! ANYHOO… Taylor also took to the gram and reciprocated the love saying QUOTE: Taylor hearts Avril with a little emoji Heart!! Awwwww… I’m so happy to see this especially after the little amount of beef that was going around last week that was completely overblown about fan drama… Lavigne’s fans were NOT happy about a post comparing Swift’s interactions with fans of other stars MEET and greets… (Including Avril) made some serious rounds on Tumblr… BUT Avril did squash this drama when she posted these words of wisdom “Comparison is judging and judging a person does not define who they are it defines who you are… She continued… “We all Love our fans” BUT MOST importantly I want to know what you all think about this epic performance?? We’re you LOVING it?? ANDDD who else would you love to see grace the 1989 tour that we haven’t seen already?
