She also went on to Italy where she performed at the San Remo Festival. It seems that her collapse was put down to being too hot whilst waiting for her flight in British Airways Club Lounge.

An eyewitness told the paper, “It was very dramatic. Susan’s legs just gave way under her and she went down.”

And Susan’s spokesman is quoted as saying, “Susan did faint at Heathrow as she overheated in the lounge because it was so warm.

“However, she is fine now and gave a fantastic performance at the festival.”

It seems that BA has a problem with Susan because last month, media reports suggested that she’d been “asked to calm down” after reportedly causing a disturbance while at Terminal 5.
