Zayn Malik has been "partying too much".
The Pillow Talk hitmaker - who recently pulled out of the Capital FM Summertime Ball due to anxiety issues - is doing his best to eat healthily after his lifestyle began taking its toll on his health.
He said: "I've not been feeling too well recently because I've been partying too much and not looking after myself and eating enough food. I'm just trying to take care of myself."
The former One Direction hunk admits the reaction to his solo material from his fans has been "overwhelming".
