The 73-year-old Australian television personality, who was hospitalised in Singapore last week with a suspected heart malfunction, will be back on stage in the touring production of musical Wicked tomorrow.
The show's spokesperson Amanda Osborne dispelled rumours of cardiac arrest, telling the Herald Sun: "He is absolutely back on track. Bert Newton has not had a heart attack or emergency heart surgery in Singapore. He has had a very heavy cold, which caused him some minor complications and a short stint in hospital."
She added that the star "has to be extra cautious" after his "bout of debilitating pneumonia" in June last year, which landed him in the intensive care unit at Epworth Hospital.
Newton's wife Patti, who is currently taking part in the second series of Celebrity Apprentice in Sydney, was unable to make it to his bedside until Friday last week due to filming commitments.
The couple's daughter Lauren had to remain in Melbourne due to being pregnant, while their actor son Matthew, who has been in and out of a psychiatric clinic since allegedly attacking former girlfriend Rachael Taylor in 2010, was recently accused of assaulting a taxi driver.
