I've got more than 600 pairs of Ray-Ban sunglasses, from 1950s originals to newer models. I have them on the wall like opticians do so I can pick out a pair that goes with my outfit. I had around 30 pairs, then my husband Rainer started getting them for me as birthday and Christmas gifts.

As Mick Jagger will tell you, performing is an aerobic work-out. I've got the bass guitar, which is the heaviest of all the instruments, and I'm a little girl, in boiling-hot leather under the lights. You have to keep the fitness level up if you want to look good up there.

There are things you're supposed to learn in life. My biggest regret was terminating a pregnancy when I was about 18. Every day, I think about who that baby would be now; it still makes me sad.

Even though my first marriage broke up, I'd say that I've had two good marriages and two good men. I've been very lucky. I like to think it's karma because, in a relationship, I give 300 per cent. I'm straight with my men, and I like to think it comes back.

One of my insecurities was my looks. I was short, cute and chubby, and Dad used to call me his 'little fat sausage.' But I always knew I had musical talent.
