Sophie Monk required paramedic assistance at her hotel room in Melbourne, Australia on Saturday (12Mar11) after the actress fell ill with severe stomach cramps.
The Date Movie star was staying at the city's Como Hotel when she summoned doctors in the early hours of the morning and was subsequently diagnosed with a bout of gastroenteritis.
Monk reportedly picked up the stomach flu from relatives who have been suffering similar symptoms and she has been advised to rest.
The former pop star's representative Alex Reid tells the Sydney Daily Telegraph, "Her family has been sick with it and it seems she has picked it up. She was advised by doctors to rest. Later that day her condition worsened.
"She's had it before. She had it about a year or so ago, only not as bad. When doctors told her what she had, she recognised it from before and then followed their advice to take fluids and bed rest."
Monk has cancelled her guest appearance on Australia's Project Runway TV show while she recovers.
