... We think the 46-year-old singer's giant smile says it all.
Stefani and Shelton's adorable PDA was also evident throughout the awards show, when they affectionately hugged and held hands after their performance.
Earlier this month, Shelton, 39, dished on his hit track with Stefani to ET's Sophie Schillaci.
"When I originally started writing this song that we're performing tonight, I was only trying to impress Gwen," the Voice coach admitted. "I started this song and wrote about half of it and sent it to her and she wrote the other half of it."
"It was just kind of something for she and I to help us feel better about what we were going through," he added, referring to both of their highly publicized divorces.
