Los Angeles: Kristen Stewart, who is often criticised for looking sullen in public, thinks she needs a "face transplant" to make her look happier when she meets fans.
The `Twilight` star, who has admitted she finds handling fame difficult, tries hard to "smile" and look happy when she is approached by strangers, but can never relax fully, reported Access Hollywood online.
"I totally am more comfortable now. I try not to have that thing that people have which is like a celebrity skin and I think that`s maybe where I run into problems," said Stewart.
"I have had so many people say, `Why don`t you just play the part? Just like, go smile, talk about whatever they want you to talk about.` It`s like, `I do, I really try to do that.` I guess I should get a face transplant or something. But it`s gotten weird. I`ve like, relinquished control," she added.
Despite trying hard to relax, the 20-year-old actress doesn`t plan to alter her persona for others.
"People are much better at doing this than I am and that`s fine and I`m getting better and whatever, but I`m not gonna try to force myself to do anything," said Stewart.
