Anna Paquin will always be bisexual.

The 32-year-old actress - who has 22-month-old twins Charlie and Poppy with husband Stephen Moyer - was forced to correct veteran TV host Larry King, 80, when he queried whether marriage means she is now a ''non-practising bisexual''.

Speaking on a recent episode of 'Larry King Now', she said: ''Well, I mean, I am married to my husband, and we are happily, monogamously married.''

Larry then asked: ''But you were bisexual?''

Anna replied: ''I don't think it's a past tense thing. Are you still straight if you're with somebody? Doesn't mean you're not, if you were to break up with them or you were to die. It doesn't prevent your sexuality from existing. It doesn't really work like that.''

Meanwhile, the 'True Blood' star - who plays Sookie Stackhouse opposite her spouse as Bill Compton in the vampire drama - admitted she relied heavily on ''creative costuming'' when shooting the programme while pregnant.

She said: ''We tried to time it quite carefully and up until the last couple of episodes there was a lot of creative costuming. And then they just CGI-ed out the bump.''

However, Anna admits she worried it would be ''creepy'' shooting a raunchy sex scene during her pregnancy, but felt it was done tastefully.

She added: ''There was only one scene that we had to shoot while I was pregnant. Bill is having this fantasy while he's having sex with Salame, who turns into Lileth, and then it turns into me.

''So I was like, 'Oh wow, it's basically a... gang bang with my husband while I'm pregnant!' But we shot from shoulders up so it wasn't like, 'OK, that's actually really creepy!' ''
