They've done a lot of work together recently, and a lot of people are speculating that Chris Stapleton may make an appearance at the Super Bowl half time show with Justin Timberlake.

It was just a few years ago when their performance of Tennesse Whiskey catapulted Stapleton's career into a household name.  Since then they've continued their friendship and have been trading music back and forth.  Stapleton just recently appeared with Timberlake on his single 'Say Something.'  He helped write several songs on JT's album and even played the guitar for his lead single 'Filthy.'

They are definitely very close right now, and that could translate into a stellar performance this Sunday in Minneapolis.  At this point I would be more surprised if Stapleton didn't make an appearance.

Now the real question is: what kind of tribute will JT have for Prince?  I mean, that's a must in the State of Minnesota.
