The singer revealed that he was left red-faced after trying mulled wine, a heated and spiced red drink, for the first time during his visit in the U.K. last year.
"When I go out I get in trouble. I can't handle alcohol that well," Contactmusic quoted him as telling British chat show host Paul O'Grady,
"You know what I tried last time I was here (in Britain)? Mulled wine, the hot wine. It's like medicine.
"It really made me feel sick. It gave me diarrhoea, it was bad. It left me drunk and with diarrhoea!" he added. (ANI)
