Celine Dion's Met Gala debut was one for the books, completing her fabulous night with a late-night treat after the event.

On Friday, the 49-year-old singer proved that no megastar is too cool for one of New York's famous street foods. "Priceless! Late night hot dog in New York fully dressed in Versace!" Dion captioned her Instagram pic, where she's seen munching on a Top Hot Dog in her custom-made black leather-and-silver Atelier Versace gown, completed with an origami-inspired headpiece.

ET caught up with the "A New Day Has Come" singer on the Met Ball red carpet, where she told Carly Steel how thrilled she was to attend the glamorous fundraiser.

"This is overwhelming, exciting, nerve-wracking, I don't know where, how to stand, where to look. [I'm] seeing everyone I see on TV, [but I'm] not quite sure if it's really them," she expressed. "I'm used to premieres, but this is my first Met Gala. I'm not quite sure I know what I'm doing. It's all like, the preparation of this whole thing, they said, 'You're gonna have such a great time, it's so fun!' Well, it might be fun in a couple of hours after a drink, but right now, it's like a shock."
