She wants Rihanna in her squad.
On the subject of celebrity squads, Adele told Rolling Stone in 2015, "I wish my squad was all supermodels. We are, in our brains. I guess I have my own squad." She added, "It’s not as interesting as some of the other squads that are around right now. But maybe Rihanna can be in my squad! That would be really cool. Oh, God. She’s life itself, isn’t she? I love her."
