'Neighbours' star Kym Valentine reportedly suffered a collapsed lung while on a flight last week.

It was initially reported that the actress began to feel unwell because of a bout of pneumonia.

However, Australia's Courier Mail has now reported that Valentine, who plays Libby Kennedy in the soap, suffered a collapsed lung on the flight from New York to Melbourne, causing her to pass out.

The report says that cabin crew gave the star oxygen during the flight.

When she arrived in Melbourne she was reportedly taken to hospital for further treatment.
