The Cabbage Soup Diet "I went on the cabbage soup diet which is a detox diet, and it is definitely all about high protein and low carbs. And I started working out at the gym with my trainer 10 days after the birth . . . five days a week for two hours every day. Today I went to McDonald's and ate two cheeseburgers. You have to treat yourself every now and then."

High protein, high fibre delivered meals and cardio workouts "I thought I looked heavier after I had the baby. [The bulge] left the stomach area and shifted into areas that I didn't know could gain weightf I was like, Uh-oh. When I first started it was hard; I've never had to diet before so I was like, 'Oh, am I going to be able to stick to this?' But I like my curves, I'm happy with the way I look. I don't think about getting down to a size 0 or a size 2 because that was before. I'm a mom now."

Sensible eating, exercise and an album release "All of my life I've had to work hard to stay in shape. I've always struggled with it. I was a little chubby when I was younger and I didn't want to be that person forever. There aren't any tricks, it's simple maths . . . you put this much food in, you burn that much working out. I gave myself three months . . . but if I didn't have an album coming out, there's no way I would have got back into shape in that time. I worked out with my trainer five days a week, with weekends off. I would really recommend doing weights."
