New Grammy Commercial Confirms Bruno Mars, Beyonce Performances

Their participation hasn't been officially announced by the Recording Academy, but a new Grammy TV ad that was briefly posted on YouTube perhaps in error is advertising that Beyonce, Bruno Mars and other acts have joined the lineup for the January 26 telecast.

In the ad, since removed, performances are promised from not only Beyonce, but also from her husband Jay-Z, which means a duet might be on tap.  The ad also teases Bruno Mars and country star Hunter Hayes, as well as performers who've already been announced, such as Katy Perry, Taylor Swift and Lorde.

On Friday, the Los Angeles Times reported that Beyonce and Madonna would both be making appearances on the show, but the Grammy folks have so far been quiet about that.
