LONDON -- Lady Gaga has canceled 10 tour dates in Europe and South America because of severe pain.

Tour promoter Live Nation says the musician is "suffering from severe pain that has materially impacted her ability to perform live."

Lady Gaga said in Saturday's statement that she's "devastated" to disappoint her fans. She said her medical team "is supporting the decision for me to recover at home."

The singer had been due to play Sunday at London's O2 Arena, followed by other concerts in Britain, Switzerland, Germany, Sweden, Denmark, France and Brazil.

Lady Gaga previously postponed her European shows in September after being taken to hospital in Rio de Janeiro suffering from "severe physical pain."

She resumed the tour in North America in November and in January played several dates in Europe.
