(Cover) - EN Showbiz - Emma Watson keeps her passionate side "bottled up somewhere".

The 21-year-old British actress is best known for her role playing geeky Hermione Granger in the Harry Potter film franchise, and with the final movie in the series scheduled for release this month, the star has been preparing to embrace different characters.

Emma admits to struggling with her portrayal of fiercer characters, as she finds it hard to release such strong emotions.

"My acting tutor said the hardest thing for me was to get angry. I almost broke down in tears when they tried to get me to be angry. I said, I can't do it, I just can't do it'," she confessed in an interview with the August issue of Harper's Bazaar UK.

"I keep all of that really bottled up somewhere and I feel unleashing it would be the scariest thing and to let myself be powerful, sexy, all those things, it's scary for me."

The star added that even posing for the raunchier images for the accompanying magazine shoot made her feel "a bit uncomfortable and awkward, it didn't come naturally at all".

Emma also explained how daunting she finds Los Angeles. The actress, who is blessed with natural good looks, never wants to get caught up in the glamorous city's image-obsessed culture.

"LA scares the c**p out of me," she confided.

"I feel if I have to work out four hours a day, and count the calories of everything I put in my mouth, and have Botox at 22, and obsess about how I look the whole time, I will go mad, I will absolutely lose it."

She also addressed her decision to leave America's Brown University and complete her studies in her native England. There had been reports Emma had been taunted by classmates, and she was quick to state this was never the case.

"Leaving Brown had nothing to do with bullying, as the media have been suggesting recently," she added.

"I have never been bullied in my life. Like a lot of other students at Brown, I might spend my third year abroad." (C) Cover Media
