The 22-year-old became well-known as a pre-teen when she landed the role of Hermione Granger in the 'Harry Potter' franchise.
In a series of posts on Twitter, she posted: "It's been 10 years but I still feel so uncomfortable with being recognised. Just a bit shy I suppose," reports contactmusic.com.
"I wish I had camouflaging powers like a superhero. That would be so helpful. Except for with kids, they are usually shyer than me so I don't feel so bad," she further posted.
