Boom!
Katy Perry has officially joined the back and forth between Taylor Swift and Nicki Minaj.
One day after the "Anaconda" rapper and the "Shake It Off" singer got into a Twitter spat over the 2015 MTV Video Music Award nominations, the 30-year-old singer has weighed in on their wars of words?and she's not holding back any of her disdain for Taylor Swift.
Essentially she called Swift a hypocrite since the 25-year-old pop star penned her hit "Bad Blood" about her ongoing feud with Perry.
