Mariah Carey has denied reports that she turned to plastic surgery to achieve her new slender figure.

The newlywed singer unveiled a svelte new look earlier this year when she began doing promotional work for her E=MC2 record - sparking speculation she has gone under the knife to drop a remarkable 32 pounds (14.5 kilograms).

However, Mariah insists that she ditched the lbs through diet and exercise alone.

She says, "I know the U.K. is freaking out that I had some crazy plastic surgery done, but... honestly, it's working out and diet. Look at what I'm eating right now: olives!

"It makes me upset that people think I've had surgery, 'cause let's discuss how annoying the dieting process was. My girls will eat really good fried food, and I also love sweet plantain and rice and peas, but I can't eat it! If I eat it, it's small!"
