In an @ post to Tomlinson, he wrote, "remember when you had a life and stopped making bitchy comments about mine ?" In this day and age, it's not unheard of for such a comment to be deleted shortly afterward (though not before it was screenshotted by hundreds of fans), but Malik's sticking to his guns--it's still there.

But why? Well, Naughty Boy, with whom Malik's been working for his solo career, posted a photo of the pair today with the caption "replace this."
