Just last week, he semi-shaded Harry Styles, saying he wasn't into his new solo music... and this week it's Zayn's turn.
As we alllll know, Zayn quit the band and created one of the biggest controversy's ever seen in boy band history, especially after he took every chance he could to drag them to hell and back.
Now, Liam spoke on radio show Bizarre Life with Dan Wooten, about a possible 1D reunion, and Zayn's involvement.
"By the looks of things, he doesn't really want to. That's on him, really."
He continued to say that Zayn, "doesn't really support the cause. So it's not like he could be. He feels hurt and scorned in some way that I don't really understand. That's down to him."
He then went on to explain how much he ~cherishes~ his time in 1D (despite his hurtful lyrics in his new song), saying that Zayn's outlook is, "very sad because One Direction was a wonderful, wonderful time in all of our lives. It was like uni, but on steroids. It was mad. It was madness. It was so much fun. I don't understand how you can come out of that experience and say the things that he says sometimes. It doesn't make any sense to me, but there you go."
Don't hold back Liam. Tell us how you really feel.
