Irish pop star Samantha Mumba has collapsed at her home, casting doubt on her appearance on British TV show DANCING ON ICE. The singer was found to be suffering severe flu symptoms and dehydration, and was hooked up to a drip by medics - with her participation on the celebrity ice-skating show now under threat. However studio bosses are reported to have called in additional medical staff to work on Sunday's (13Jan08) live broadcast. A source tells British newspaper The Mirror, "She was very sick but is resting now and is determined to get better and get back on the ice."
