Zayn Malik is "angry and upset" after he was accused of missing a One Direction promotional appearance on Monday (17Nov14) because of substance abuse issues.

The singer was missing from the line-up as the band performed a free televised show at the Universal Studios theme park in Florida on Monday to promote their new album Four.

During the Tv appearance, Today Show host Matt Lauer caused controversy by asking the pop stars whether their colleague is dealing substance abuse issues, and his bandmates insisted his absence was down to a stomach bug.

Malik has now spoken out to dismiss the allegations himself, admitting he is furious with the host for making the suggestion on Tv in front of so many fans.

He tells Britain's The Sun newspaper, "I'm really angry and upset by what was said on the Today show. I was really ill at the weekend, that's why I couldn't go to America... As soon as I'm feeling better I'm going to join the guys and carry on with the promotion for the album... I was gutted to have to miss album release day. But I'm going to be back as soon as I can."
