Sarah Harding feels "possessed" when she performs live

Sarah also admits she has extreme mood swings, but insists her volatile
personality fuels her ambition to be successful.
The 27-year-old blonde star told GQ magazine: "There are different sides to
me. I am an excited puppy or a dead dog. I have big fat bursts of energy and
then I can be really moody.
"I would get bored if I was stuck doing the same thing year after year. I
always want to do something different. I would love to do a costume drama
next."
Sarah - who appears in new UK TV drama 'Freefall' - recently revealed she
would like to launch a theatre career after Girls Aloud eventually split.
