If Taylor could calloborate with anyone of your dreams who would it be??

if Taylor Swift could calloborate with any artist of your dream who would it be and why?? also what song would you like them to sing, a Taylor song, the other artist songs, a remix of both or a original song that both of them have worked on??

i would choose Avril Lavigne because she is my favourite artist and i think because they both have unique voices it would sound good! i think it would be cool if they wrote an original song together because they are both talented artists so i would like to see the do a duet.

please tell me who you would like xx
