Forget fighting in the streets and take it to the tweets!
It all started on Monday, Oct. 7, when Louis complained on Twitter about his temporary housing sitch, writing, "It's a beautiful day and we can't leave the hotel #papsaretwats."
Well, per Sugarscape, Nick alluded to the boy-bander's tweet on his Radio 1 Breakfast Show, calling Louis a "complainy pop star."
Oh, goodness. Louis was not amused, and tweeted a subtle diss at Harry's pal, writing, "@grimmers < chrisjmoyles [another British radio presenter]."
Chris Moyles, the aforementioned BBC Radio 1 host who's greater than his 1D-dissing competitor if you ask Mr. Tomlinson, weighed in jokingly. "Not really sure what's going on today on Twitter," he tweeted. "In other news, isn't @Louis_Tomlinson a talented, handsome boy!"
That he certainly is.
And while Harry, Niall Horan and Liam Payne appear to be staying mum in the war of words, Zayn Malik made sure to publicly take Louis' side. "Don't know why people always have to get brave ? Mind your own business :)," he wrote. "@Louis_Tomlinson love ya bro. !"
In the end, bromance conquers all.
