Justin Timberlake‘s upcoming Superbowl Halftime Show performance on Sunday might become just as controversial as his last appearance with Janet Jackson if new reports are to be true.

Folks have been speculating if h was planning to bring Janet Jackson, N’Sync or Britney Spears out as special guests, well according to TMZ, none of those is happening. but he will be bringing out another special guest, the late and great, Prince–via Hologram.

Sources inside rehearsal tell us JT did 4 run-throughs, just on Thursday. We’re told one was a dress rehearsal that was taped for emergency … just in case anything happens to JT and he can’t perform.

This video is from one of his Thursday sessions, and one thing’s for sure … there’s gonna be a TON of fireworks inside the U.S. Bank Stadium.

Our sources also reveal there are no ‘NSYNC or Janet Jackson cameos planned … so anyone hoping for a reunion or redemption … you can pretty much abandon all hope.

HOWEVER, we’re told Justin does have one pretty cool trick up his sleeve — a hologram to honor … wait for it … Prince, in his hometown.

Of course, plans and strategies can change … but an overhaul at this point seems unlikely.
