Anna Paquin thinks plastic surgery would limit her as an actress.

The True Blood star - who is currently pregnant with her first child with husband and co-star Stephen Moyer - isn't always happy with her looks but says she wouldn't change a thing because her physical quirks bring her a greater selection of roles than if she had a generic Hollywood look.

"Interestingly enough, I don't really care about my teeth, but I think any woman on this planet could say, 'I wish my ass was smaller, my arms were thinner and I had green eyes not brown.' I think anyone is as critical as they have the energy to self-obsess, but I also know as an actress you are more limited if you interfere with your looks. If you have a whole bunch of work done with your teeth and your face and your boobs then you're only going to play modern people. That's a big choice to make. Very limiting."

Anna, 29, also revealed she has been shocked by the ignorance of some people towards her because of her bisexuality.

"I'm sure for some people saying they're bisexual feels less scary than making a statement that they're gay. For me, it's not really an issue because I'm someone who believes being bisexual is actually a thing. It's not made up. It's not a lack of decision. It's not being greedy or numerous other ignorant things I've heard at this point. For a bisexual, it's not about gender. That's not the deciding factor for who they're attracted to."
