Hunt, who began his performance sitting in a seat on stage, quickly ran down to the audience, where there was a seat conveniently empty right next to Fowler.

ET caught up with Hunt on the red carpet, where he couldn't stop gushing about his upcoming wedding to Fowler, and what it means for his spotlight-shy fiancee to be supporting him at the show.

"It means a lot [that she's here with me]," he told ET of Fowler, who he's been dating on and off since 2008. "This change of lifestyle happened when the two of us weren't dating and together, so I've been introducing her to my new life a little bit at a time over the last 6 months."

"This is a big leap compared to some of the small steps we have taken so far, so I hope she enjoys it, it's a radical change for sure, but she is optimistic and I am proud that she is out here with me." he said. "She looks gorgeous and she's feeling good, smiling, so that's a good sign."
