It's no secret that the pop sensation group One Direction has captured the hearts of fans around the world and last month, when Zayn Malik failed to make an appearance on the Today Show, fans were eager to find out why.

During the appearance in Orlando, the members of 1D, minus Malik, promoted their new album Four, and when Malik failed to show up, Matt Lauer asked the question on everyone's mind.

Lauer asked if the heartthrob missed the appearance because of his rumored drug abuse and after his band mates and Malik shot down reports of substance abuse, Malik reunited with the other members of the group.

Since his return, 1D stole the show at the AMA'S after giving the performance of a lifetime, and winning every category they were nominated for, but now Malik seems to be absent again.

On Saturday, Niall Horan posted a photo with the group and retired Dutch footballer, and Malik was obviously missing.

 Met this legend today! what an incredible player he was, one of the best finishers ever ! RUUUUUDDDD!

Of course fans are eager to know where their beloved 1D member is, and if he's missing because those rumored substance abuse allegations are in fact true.

On Sunday, Niall took to Twitter to share a photo of all of the boys together and he simply captioned the photo, 'Yesterday!' Perhaps he posted this photo to slam any more reports of drug abuse.

It looks like all is fine with the members of 1D, so everyone can relax.
