Britney Spears may be taking notes from Simon Cowell because she's not holding back on "The X Factor USA."
In a promo video released this today, Britney is brutally honest with contestants saying things like "you definitely don't have the X Factor" and "I wanna know who let you on stage..."
Showcasing the fact that she knows music, Spears also takes on a contestant that simply ruined a song.
Watch below:
The X Factor USA premieres Wednesday, September 12 at 8/7c on Fox.
