(Cover) - EN Showbiz - Emma Watson has lamented the effect of being one of the most famous young actresses in Hollywood.

The Harry Potter star took to Twitter today to say she is actually quite timid and being well known still hasn't caught up with her.

The 22-year-old starlet revealed that she wishes she had the power to go unnoticed.

"It's been 10 years but I still feel so uncomfortable with being recognised," she wrote on the social networking site. "Just a bit shy I suppose."

"I wish I had camouflaging powers like a superhero. That would be #sohelpful.

"Except for with kids, they are usually shyer than me so I don't feel so bad."

Meanwhile, Emma is reportedly in talks to take on the role of Anastasia Steel in the movie adaptation of hit novel Fifty Shades of Grey.

She is said to be the favourite of producers Mike De Luca and Dana Brunetti.

They apparently feel that along with her great acting ability she has a measure of innocence needed to play the young graduate that is swept up into the world of sadomasochism with billionaire lover Christian Grey.

Elizabeth Olsen, Mila Kunis and Kristen Stewart are also said to be among the hot contenders for the coveted role. (C) Cover Media
