Liza Minnelli will perform next week, despite collapsing during a Swedish show three weeks ago.
The 61-year-old singer collapsed as she was walking offstage in Goteborg, Sweden, on December 12 and returned to the US the following day to seek advice from her doctors.
However, Liza's lawyer Allen Arrow has reassured fans "not to worry" about the star, and insisted she will be ready for her performance in Providence, Rhode Island, on January 12.
While refusing to comment on the specifics of Liza's collapse, Arrow said: "She was that sick. You wonder why she had the courage to get on the stage when she shouldn't have."
Liza - who is scheduled to perform across the UK in May - won an Oscar and a Golden Globe for her portrayal of Sally Bowles in the 1972 film 'Cabaret'.
The star - who has three Tony Awards to her name - also won an Emmy for her 1972 TV special 'Liza with a Z'.
