"A lot of people hear the song and they think it's about an ex-boyfriend or something like that, but it's actually just a song about the haters," Lovato told Amazon Music. "[It's] a song to the haters that is basically saying, 'You know what? I'm good now. And sorry I'm not sorry that you may not be loving where your life is at the moment."
Lovato said the "Sorry Not Sorry" music video -- which features cameos from Wiz Khalifa and Paris Hilton -- was inspired by a house party she threw a couple months ago. And despite the connotation of the song's title, Lovato said it's actually very "lighthearted."
"It's not as intense as you think it is," she said. "It's a lighthearted song, and so the video is going to be lighthearted, too. You don't want it to seem angsty. You don't want it to seem angry by any means, so the video is going to be a giant house party."
"Sorry Not Sorry" is the lead single on Lovato's untitled sixth studio album. Her last album, "Confident," was dropped in 2015.
