The singer insisted having assistants on hand for her Jack Russell pooches Cha Cha and JJ while filming a recent commercial, but insists she is not a diva. She told Britain`s Hello! magazine: "My puppies are starring in this ad with me, too. I had my team with me but the pups had a mini entourage of their own, of course! And why wouldn`t they? It was a big shoot and even my entourage had an entourage - my stylist had an assistant, my security had extra security. "The shoot was based on the fact that some people think I`m a demanding diva. I have no idea why people have that impression!" The `Fantasy` singer has previously admitted to feeling baffled by her "demanding" reputation. She said: "I am baffled, shocked and appalled when I am called a diva. I`ve never done one diva-ish thing in my life. The actual definition of a diva is a woman who sings well. "The secondary definition is a woman who is difficult to deal with. I hope I am the first, but I really don`t think I am the second. I don`t believe I am truly nasty and act in a bad way."
