Beyoncé and Jay-Z to Open 2014 Grammys?

They recently collaborated on her surprise album and now Beyoncé and Jay-Z are set to take to the stage together on the biggest night in music.

According to reports, the Single Ladies hitmaker and her rapper husband will be the first act to perform at the 56th annual Grammy Awards.

The couple's appearance was confirmed in a CBS commercial for the awards telecast, which was quickly removed from the web, according to Billboard.com.

Speculation is rife over what song the couple will perform as they have a number of duets under their belt.

While their track Part II (On The Run) is up for Best Rap/Sung Collaboration at the awards, they have previously teamed up on songs like "Crazy In Love," "03 Bonnie and Clyde," and most recently, "Drunk in Love" off Beyoncé's self-entitled visual album.

It will be Queen B's first public performance since the release of her fifth album.

Meanwhile Jay-Z will be going for Grammy gold after his 2013 album Magna Carta Holy Grail bagged nine nominations.

Other acts set to perform on the night include P!nk, Kendrick Lamar, Imagine Dragons, Robin Thicke, Macklemore, Ryan Lewis, Taylor Swift, Bruno Mars and Katy Perry.

The Grammy Awards is scheduled to take place at the Staples Centre in Los Angeles on 26 January. It will be hosted by LL Cool J.
