Martine: I don't tend to parade around naked - I hate a man to see my naked bum wobbling when I'm on my way to the loo in the morning. But I've not had any complaints!
Martine: They've been really positive in LA. They said I'm England's answer to Jennifer Lopez.
Martine: (on her miscarriage) Everything happened so quickly, I'm still in a state of shock. One minute I was two months pregnant and going to be a mum, the next it was all over. I'm devastated. It's just so hard to deal with.
Martine: (on her role in the West End Production of 'My Fair Lady') I didn't play the part as often as I hoped I would or as often as others hoped I would. When I did play that part, it meant the world to me and it changed my life. The opening was the happiest night of my life. It beats relationships and romance and anything.
Martine: I used to worry about what the public thought of me, but I've learned to live with who I am. I'm far happier as a result.
Martine: I think all women feel more beautiful when they're in love – we just glow.
Martine: (on doing lesbian sex scenes for The English Harem) There are sex scenes with other ladies. I'm a straight woman so I wasn't worried about there being any sexual chemistry. I just wanted to giggle all the time, especially when the director was shouting, 'More thrusting'.
Martine: (on her abusive childhood father) My first memory of my dad is him hanging me over a balcony. I remember just hearing the voices and feeling scared. I can remember hearing my mum reassuring him and him threatening to drop me if she didn't do what he said.
Martine: (on Hollywood) Los Angeles is just brutal. Even Cameron Diaz is old hat. Once you do three movies, you're over. I can see why people like Kate Winslet have said they like spending time in the UK - Los Angeles just isn't the real world.
Martine: I'm not actually Tiffany from Eastenders, contrary to what some people seem to think!
Martine: Some men send me condoms and underpants. I'm not sure what they want.
Martine: My duvet is one of my favourite things.
Martine: I love to snuggle up on the sofa wrapped in my duvet watching old black and white films, and catching up with friends and family on the phone.
Martine: (on the rigors of shooting Love Actually) I've spent the last four days snogging Hugh and he is a really good kisser.
