Dancing on Ice contestant Samantha Mumba has revealed she almost pulled out of the reality show because of a frightening condition.
The Irish singer, 24, admits she 'has no idea what's going on' with her body.
'I've been having heart palpitations which are very weird and scary,' she says.
'It's really, really bad timing. I was already 4 weeks behind the other dancers as I had a bad knee injury.'
Sam became ill when she returned to London after spending Christmas in California.
'I went to the doctors for tests and basically I have no iron whatsoever,' she tells the News Of The World. 'Stress might be a factor too.'
Despite her anxiety, the idea of having to drop out of the show was 'heartbreaking'.
'It was one of those things that I had to face up to as a possibility,' she admits. 'I kept thinking, "God I hope I'm actually OK".'
Sam was back on the ice on Saturday night but ended up in the bottom 2 with TV presenter Sarah Greene.
She was saved by the judges' vote.
