Zayn Malik threw major shade at Taylor Swift's campaign for better music streaming services, and her boyfriend Calvin Harris is just not having it! The DJ totally slammed the former One Direction singer for making fun of the 1989 pop star's comments about Spotify.
The Armani model launched into a scathing tirade about how the Bradford Bad Boy didn't understand what his girlfriend was saying, and that it's time for Zayn to "stay out of things you don't understand."
Needless to say, the former 1D guy was not happy, and totally lashed out at Calvin, basically calling the DJ an old man (for the record, he's 31 years old and Zayn is 22 years old) and dissing him for not writing his own music. Just wait until you see what the Bradford Bad Boy said — it's pretty saucy.
