The list of performances and presenters for the 2014 Grammys on Sunday keeps getting more impressive.

We told you last week that Madonna and Beyonce were likely to perform at tomorrow night's award show and it's been confirmed. Beyonce will perform something from her new album released last month. As for Madonna, initial word was her accompanying another performer, but...it's Madonna! Who knows what she has in store for viewers.

Julia Roberts has been added to the list of presenters. Also presenting will be Jeremy Renner, Steve Coogan, Charlie Wilson and more. LL Cool J is once again host.

Should make for an exciting three-and-a-half hour show (our guess is it will go over)!

The Grammys air Sunday, January 26th beginning at 8 p.m. on CBS.
