Stefani looked stunning with big, wispy blond curls à la Marilyn Monroe, and wearing a flowing goddess gown while crooning the song she said she wrote in the aftermath of her painful breakup with ex-husband Gavin Rossdale — said to have been caused by him cheating on her with the couple's nanny, Mindy Mann.
Watch her performance below.
The emotional middle finger to her ex brought new boyfriend Blake Shelton to his feet for a standing ovation.
Stefani previously told Carson Daly that the inspiration for the song came "the day after some crazy stuff had gone down, like, crazy stuff in my life. I've been writing stuff randomly, like, instead of going online and looking at stupid stuff, but being like, 'I'm just going to write. This is how I'm going to heal. I need to write.' And I went back in and found that lyric and then it ended up being the chorus of the song."
"I don't have anything to hide. Everybody knows that I was married forever and now I'm not. So, could you imagine what my life is like right now? It's crazy! I ended up going into the studio. On the way to the studio, that first time, I didn't want to go. I wanted to be in my bed, crying. And I did cry all the way down Santa Monica. 'What am I doing? Why am I doing this?'"
It seems Shelton has successfully dried Stefani's tears.
