Dressed in an ombre draped halter neck Marchesa gown with a perfectly styled top knot, the platinum blond beauty was all smiles while thanking Shelton for everything he's done for her this past year.
"I'm so grateful for everyone around me that helped me this year. It was a magical time, and I just want to say thank you to my parents for that gift of faith," Stefani, 47, exclaimed. "I want to say thank you to anyone that has ever listened to my music, I am so honored and grateful. And to my children, to my family, to Blake Shelton for kissing me back to life, thank you so much. I am blown away!"
The camera panned to the "Came Her to Forget" singer, who adorably flashed a smile as Stefani said his name.
Stefani was incredibly moved by all the support she's received from friends and family following her divorce from Gavin Rossdale last August. The two split after 13 years of marriage, around the same time Shelton called it quits with Miranda Lambert.
"Honestly, no way, in my life would I have ever dreamed that this would be happening to me right now. I never thought I would touch anyone's lives or make an impact in any way," she explained in her speech. "I just want to say that I was on my way here, driving by myself in the limo, and I was like, 'How did this happen to me? How did I get here? How did this happen this year?'"
"I was just thinking back. I was thinking about my parents, and I was thinking about my mom and dad, the greatest mom and dad in the world, that love me the most out of anyone," she continued, holding back tears. "They planted a seed inside of me when I was a little girl and it was a seed of faith, and if I didn't have that this last year -- this year was incredible, by the way -- it was a year and a half ago, I was in a pool of tears. I was so disappointed, and I was so low that I didn't think there was any way that I could pick myself back up, but I just remembered that God gave me a gift, and I just wanted to use that gift again so badly."
"I knew I had to do it, and I knew that that's what my responsibility was, because I knew I was chosen to do that," she added. "So I just basically started pouring my heart into music, and music has saved my life. I never thought that I'd have this gift to do music, I don't even know where it came from, but I'm so honored to be able to share my story. I'm so honored that I got to make a record [This Is What the Truth Feels Like] at this point in my life, and share my story with people, and exchange that love back and forth."
And love was certainly in the air for Stefani all night long, as Shelton couldn't keep his eyes off his gorgeous gal. While the two were chatting with James Corden, who presented the No Doubt frontwoman with her Woman of the Year award, Shelton seemed to pay no mind to The Late Late Show host's jokes.
ET caught up with Stefani on the red carpet for the fancy fête, where she echoed her sweet sentiments about how Shelton saved her life. "It's incredible to have a best friend like that guy," she marveled. "He's an amazing person."
