London, Sept 10 : Britain's Got Talent runner-up Madhu Singh, 34, sparked off concerns about his health when he collapsed on stage at a charity bash.
The member of the dance group Signature shocked the crowd when he fell down after their act, and doctors had to be called in to treat him.
"They have been working very hard with few days off," the Sun quoted the group's booking agent as saying.
"They are really tired, but Madhu is fine now," the agent added.
The incident occurred at the Red Carpet Bash last week at London's Grosvenor House hotel.
Singh splits his time between performing with Signature and working in a branch of PC World at Heathrow Airport.
