Songstress Adele has told fans she had to stop eating pizza to protect her voice. The 28-year-old told fans in Los Angeles that the cooked tomatoes could damage her throat and voice. She said: “I'm in America and I can't eat pizza no more. It's worse than Romeo and Juliet. If only Shakespeare was alive, he could write about it." The ‘Hello’ singer is currently travelling around America on her 25 Tour.
