Last night, Calvin Harris got into a bit of a Twitter spat with former One Directioner Zayn Malik after he thought Zayn was saying something negative about his number one special lady, Taylor Swift. That beef calmed down pretty quickly, with Harris even generously telling Zayn he had a great voice. But the eagle eyed research team at E! News points out this isn't the first time Harris got into a spat on Twitter — in 2011 he and noted Taylor Swift nemesis Katy Perry got into it on Twitter over him pulling out of her show, and he also once insulted the songwriting abilities of Lady Gaga, who called him out on Twitter about it back in 2012. All of these people need to just pick up the phone and call each other.
