It was just revealed that one particularly famous group lent their voices for the backup vocals of the song after gaining some praise from Yeezy. Can you take a guess as to who it is?
Nope, it's Wendy Wilson, Chynna Phillips & Carnie Wilson, otherwise known as Wilson Phillips!
"[Kanye West] said, ‘When I think of authenticity and I think of angelic, I think of you,'" Carnie told Billboard. "He was really shy and he would just smile and he's real soft-spoken, then all of a sudden when he started playing all these songs, he was dancing around the room," she continues.
"It was just like how Michael Jackson used to be. When he would press play, it was like, out came the artist and the creativity was just really there."
According to the article, West instructed Wilson Phillips to take the track home to work on their vocal harmonies.
"We didn't know if we were singing on a section of the song—originally it was supposed to be just the bridge," Carnie says. "He gave us sole freedom to just do what we do. We just went in there and let loose."
RiRi, Kanye and McCartney teamed up for the emotionally charged black-and-white video, which doesn't feature any special effects or anything out of the ordinary, just the three performers giving it their all while dressed completely in denim.
The stripped down feel for their video was pretty much the same concept when the trio took the stage at the Grammys this year to perform the new single. No hoopla, just vocals, and it was perfect.
