Unless you don't use the Internet, you probably know that Zayn Malik and Calvin Harris involved themselves in a not-so-friendly feud on Twitter earlier today.
It all started when Malik retweeted a (now deleted) photo comparing Taylor Swift and Miley Cyrus' differing views on music streaming with the response "G statement" -- clearly taking Cyrus' side over Swift's. This didn't sit well with Harris who quickly took to Twitter to defend his (usually outspoken) girlfriend.
Naturally, fans were anxiously waiting for another celebrity -- Taylor Swift? -- to get involved. The coast was clear ... or so it would seem. Turns out, Louis Tomlinson sneakily involved himself by subtly taking a side.
After doing some investigative sleuthing through Tomlinson's Twitter, you can find that he favorited Harris' original tweet to Malik. Interesting, right? It appeared Tomlinson and him had squashed their Twitter beef after Malik's departure from One Direction. Then again, maybe not.
