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.

She told Zooeymagazine: "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.

She said: "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."
