She's the stunning model who made a big splash handing out the awards on Emmy night.
She says she found presenter Heidi Klum trying to sneak a peek at the name of the winner before she was called on stage.
Santo told INSIDE EDITION, "She gets the envelope and was trying to look at the winner. I'm like, 'Heidi Klum, you're not allowed to do that.' She looked at me and said, "I didn't do anything wrong.' "
Santo escorted the winners off-stage and was the first to speak to them as the moment sank-in. Claire Danes made a big impression.
"She said, 'You know, it's gratitude. It's awesome,' and she was trying not to cry," recalled Santo.
