Susan Boyle: 'I'm Like The Incredible Hulk'
Scottish singing sensation Susan Boyle has admitted she suffers mood swings, likening herself to the temperamental Incredible Hulk.
The star has had a string of well-publicized meltdowns, most notably checking into rehab shortly after appearing on 2009's Britain's Got Talent. She also hit the headlines last year after she became embroiled in an argument with her assistant at a Japanese airport during a promotional trip.
Boyle blames the incident on being tired and overworked - but confesses she does have issues with her temper.
Appearing on Piers Morgan's Life Stories, she reveals, "I was really tired then, I was up and down like a yo-yo. Not nice. I have got a temper, I'm like the Incredible Hulk."
