Girls Aloud's Sarah Harding was taken to hospital following a reported hotel bust-up with her boyfriend.
The singer, who checked herself into rehab last year after suffering from alcohol and depression, is said to have clashed with her boyfriend on a skiing holiday in Austria.
Sarah was taken to hospital after the fight broke out at the Hotel Schloss Matzen near Innsbruck. She was later pictured looking bruised and had a bandage on her arm.
A guest at the hotel told The Sun: "There was banging and screaming and a few guests came out into the corridor.
"It sounded like a terrible fight. By the early hours people had had enough and someone called the police. It was obviously a very serious tiff indeed. There was a lot of screaming and shouting."
A source said her lips were "swollen" and she had "puffy eyes".
Adding: "Sarah was taken to hospital because she was hysterical after the row. She was crying and screaming and clearly in a lot of distress."
The news follows on-going rumours that Girls Aloud are set to reunite in 2012 to mark their 10th anniversary
