Teen star Lorde was forced to postpone a promotional trip to the U.K. last month (Oct13) after falling ill.

The New Zealand-based singer failed to witness her hit track Royals rocket to number one in Britain after she ended up in hospital to receive treatment for a kidney infection.

Lorde, real name Ella Yelich-O'Connor, tells British newspaper The Sun, "I've been so poorly that I missed out on my success in the U.K. I was vomiting for days with a fever, so I'm just glad I made it over to the U.K."

The singer is currently in Britain promoting her debut album Pure Heroine.
