One eyewitness shared, "He went one way and she went the other. She whined to her makeup artist and assistant, 'How could he do that to me on camera?' "

However, representative for the Disney darling was quick to come up with a denial. To E! Online, her rep insisted, "Absolutely not true. Selena didn't even give it a second thought."
