While Taylor Swift has been seen all over the world doing her thing with new boo Tom Hiddleston, Tay Tay's ex Calvin Harris has been busy up in the studio... and he's about to release the final product. Taylor you might want to watch out!

According to reports, Calvin is dropping a track featuring singer John Newman this week which is all about her supposed cheating ways. The song is apparently sung in the point of view of Tom.

Another line in the forthcoming song appears to reveal his feelings about how the end of their relationship went down: 'I see online that you begun to be a good girl and take trips with your boyfriend. Being attentive, continue to pretend...'

BURN! What do you think? Will this be a major hit? Or will shots be fired quickly back by Taylor? #BadBlood
