Zayn Malik’s recent absence from One Direction’s first day of promotion for their recently released album ‘Four’ sparked a slew of baseless rumors, the most scandalous of which was brought up by an unabashed Matt Lauer. The journalist asked the boys whether the (totally unsubstantiated) substance abuse rumors had any truth to them in regards to Zayn. The rumor was shut down pretty quickly, with Zayn later making a statement via The Sun about how much the question had upset him.

When he finally rejoined the boys in Orlando a day later, Directioners everywhere rejoiced. And now, it looks like we have a more specific reason as to why Zayn didn’t show that first day. Leave it to the shameless Louis Tomlinson to embarrass his bandmate: "He's got a poo problem," Louis told E! News. "And that's the truth and he's really not gonna like me saying that.”

So, there you have it. Looks like Zayn was suffering from a pretty bad case of the runs — and we’re not talking about his vocals.
