London, Jan 27 (Inditop.com) British pop star Lady Gaga is nursing an injury on tour after burning her arm by a hair curling iron.

The singer prompted speculation when she was spotted on stage in New York last week, sporting several large burn marks on her left arm.

It was suggested GaGa may have hurt herself swinging from ropes during her energetic stage routine, but the star’s publicist has revealed she suffered the injury backstage while styling her own hair, reported contactmusic.com.

“The burns were caused by a curling iron,” said her spokesperson David Tomberlin.
