There are literally four major artists out right now that would even consider pulling a Beyoncé with a new album: Adele, Madonna, Rihanna, or Nicki Minaj. If Rihanna was spotted in the studio yesterday, there's no way it would be her. I don't think Adele would pull a Beyoncé like that, which leaves only Nicki and Madonna, so it's probably one of them. Nicki said she wouldn't do that, though, right? That leaves only Madonna, so it's probably her.
