One of the biggest moments of Emmy night happened during the award for directing a variety special.
Glenn Weiss, who won for directing the Oscars telecast, began his acceptance speech by mentioning that he had lost his mother two weeks earlier and that she was his biggest fan.
He also took a moment to thank his girlfriend, Jan Svendsen, for being the "sunshine" of his life. The couple met in 2001 while working on the Tony Awards.
"You wonder why I don't want to call you my girlfriend?" he said. "Because I want to call you my wife."
The words were barely out of his mouth before the audience erupted in applause. As the audience stood and cheered, Svendsen got out of her seat and nodded yes and made her way toward the stage.
"I didn't even ask yet," Weiss joked.

"This is the ring that my dad put on my mom's finger 67 years ago," he said. "Jan, I want to put this ring, that my mom wore, on your finger in front of all these people and in front of my mom and your parents watching from above. Will you marry me?"
He then dropped to a knee. Svendsen nodded her head, and the two of them embraced to more applause.

Backstage at the event, Lara Spencer asked Weiss what was more exciting: winning the Emmy or proposing.
"By far this," Weiss said, motioning to his fiance. "It's not even a question or a contest."
Weiss said that he and Svendsen have been together for a decade but he was waiting for the perfect moment to pop the question.
"I think I found it, by the way," he said.
Svendsen told Spencer she was "completely shocked" by the proposal.
"I'm used to being at awards shows with him and I'm used to my little one-second cutaway when he wins, so I was expecting that moment but I was not expecting what came next," she said.
"I'm the happiest girl and he makes me the happiest and I'm so excited," Svendsen added. "I'm still so shocked, I'm shaking."
Weiss said the only person he confided in about the proposal was his dad. Asked what he would have done had he not won, "Waited till next year? No, I suppose the ball or In and Out burger, which is our staple after awards shows."
He added, "The timing just lined up very nicely. It was a really magical moment."
