Music's biggest night is just a night away and music's favorite couple is set to tear up the stage at this year's show.

In a commercial earlier this month (on Jan. 19), CBS announced that Beyonce and Jay Z would be performing at this year's GRAMMYs, airing tomorrow night (Jan. 26). And in hopes to get fans even more excited, the ad promises that their performance will happen within the first hour of the show.

Though there has been on official announcement about the duo's upcoming appearance on the broadcast, it's been reported that the two will hit the stage together for a performance of their GRAMMY-nominated duet "Part II (On The Run)" off Jay's album, 'Magna Carta... Holy Grail', along with Bey's song "Drunk In Love."

Beyonce earned only one nomination this year for Best Rap/Sung Collaboration for her duet with Jay -- Her self-titled visual album came out after the nominations were already announced -- but Jay earns the title of the most nominated artist of 2014 with nine noms, including Best Rap Performance, Best Rap Song, Best Rap Album and Best Rap/Sung Collaboration, where he's nominated with both Beyonce and Justin Timberlake for their song "Holy Grail."
