(On finally having her ears pierced) At first, it felt a bit strange to have them done, but I soon got used to it. Now, I really love them and keep wondering why I waited so long to have them done.

I love my engagement ring. It is the only thing I wear to bed!

I just love to shock people. Yesterday my friend said, "What a great top, is it Stella?" I said, "No, it's Mango, £25." I'm never head-to-toe in anything. I like to mix things from Prada, things from Marc Jacobs. But, you know, you can spend several thousand pounds on something, wear it for one day and the button falls off. I get really pissed off when you spend so much money.

I love wearing flat shoes, but I am not one of those girls who walks around in sweat pants and sneakers. I think I have something going on with shoes. Flat shoes. I buy them in several colors at once. High heels are for work and they have always been uncomfortable for me. I'm amazed when I see mothers wearing high heels. If your kids run off you can't run after them.

I love being pregnant. You can do whatever you want. You don't feel guilty, because I used to feel guilty about having a day off. And, you know, something really strange happened to me. Before my pregnancies, I was someone who had to watch their weight.

I used to work every single day and travel round the world. I worked weekends, I never took one second off. When I met my husband I said, "You know what, this is important. I'm not going to work weekends any more." And when I had kids, I became even more careful. Modelling work is fine because you can do one day here, two days there, you're never long gone.

I always wanted to be less tall. When I was at school I was the same height as all of my girlfriends and then suddenly I was turning 12 and almost overnight I got really tall. I became the height I am now from one day to another... and everyone else stayed short. Boys don't want to be seen with a girl that is taller than them. It was totally isolating because I was different from my friends.

(on turning down appearing in Playboy in the nude): "It's not that I'm against nudity. I'm German, I'm very open, in Germany they lay in the park naked. It's just the principle."

I actually don't meet very many men because they are, I guess, afraid to approach me or think that I'm from another planet. - on turning 30, to the German magazine Stern

I know one day I'll be considered too old. I think 40-year-old women actually look more healthy and fit than some girls in their 20s. I've met women who have way better bodies in their 40s because they've been working on them for all these years.
