We're told at this time, there have been no final decisions on who may join Rihanna, but she will absolutely have the final say. Our sources also tell us there's still a chance she does the whole thing solo and without a guest ... though it's likely she'll have at least one person.
As we reported, Rihanna and boyfriend A$AP Rocky were spotted hitting a New York City recording studio Monday night, so it's possible they're working on something together -- maybe even for the big game.
TMZ broke the story, Rihanna will be Super Bowl LVII's halftime headliner.
