Alicia Keys is back on the road after overcoming her throat problem.
The singer cancelled concerts in Pittsburgh and Cleveland last week after suffering from swollen vocal cords.
However, Alicia recovered in time to return to action in Columbus at the weekend. Alicia's spokesperson blamed the cold weather in New York for her problems, after the singer recorded a TV appearance in the city.
Theola Borden said: "It was really cold outside. That was a bit strenuous on her. Afterwards, she went to rehearsal in Pittsburgh but wasn't feeling up to par. She felt she needed to cancel rather than give a sub-par performance."
Alicia isn't the only person on the tour to suffer health problems. Support act, and 'American Idol' winner, Jordin Sparks is currently undergoing medical treatment and has been forced to rest her voice until next month.
