It has been business as usual for the One Direction boys in Foxwoods, Mashantucket, even though they are one member light.

The boys are going down a storm in the US as they continue their tour supporting boyband Big Time Rush.

However, they are soldiering on without Zayn Malik because he had to return to the UK earlier this week, after a family bereavement. Harry Styles revealed the news on Twitter writing:

Zayn has suffered a loss in his family & has had to go home for a few days so won’t be at our next shows in the US……Our thoughts are with him and his family at this sad time.

And the American fans seem to be missing him already.

One tweeted:

Seeing videos of the boys performing without Zayn, makes you realize that One Direction won’t be the same if one of them ever leaves..

It seems that Liam Payne, Niall Horan, Harry Styles and Louis Tomlinson feel the same, as apparently they refused to introduce themselves as One Direction on stage last night, because they insist they are not a band without Zayn.

A fan commented: The boys introduced themselves as Niall, Harry, Louis and Liam instead of One Direction. Cause 1D isn’t 1D without Zayn. How very sweet! The boys next stop will be Washington where they will perform, once again without Zayn.
