My temper is like the Incredible Hulk: Susan Boyle

London: Scottish singing sensation Susan Boyle suffers from tremendous mood swings and has compared herself to the temperamental superhero, the Incredible Hulk.

The 49-year-old singer, who catapulted to fame with the hit reality TV show `Britain`s Got Talent`, also hit the headlines last year after she got into an argument with her assistant during a promotional trip, Contactmusic reported.

However, Boyle blamed the incident on being tired and overworked but insisted that she does have issues with her bad temper.

"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," she said during an appearance on Piers Morgan`s Life Stories.

The `I Dreamed a Dream` star has had a string of well-publicised meltdowns, most notably checking into rehab after failing to win the talent show.
