Zayn is flying back to UK

Harry Styles has let fans know that Zayn Malik has had to leave the US.

The One Direction boys are having fantastic success in America – but will have to carry on as a foursome without their band mate for now.

‘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…Harry, 18, Tweets.

‘…Our thoughts are with him and his family at this sad time.’

1D caused chaos in Toronto when they made their first appearance on Canadian TV this week.

Officials shut down the street outside the Much Music headquarters after they struggled to control screaming One Directionettes gathered behind metal barriers.

The boys, who are touring with Big Time Rush, later performed a gig in the city.
