will.i.am to present Grammy

The organisers revealed all in a tweet this morning, "OFFICIAL! will.i.am (@iamwill) and @ClayMatthews52 will present at the 53rd GRAMMY Awards!"
It will complete an incredible week for will.i.am who last Sunday performed during half-time at the Superbowl.
It's also be announced that Bob Dylan will be appearing with Mumford and Sons.
Eminem has got 10 chances of winning a Grammy this weekend but he's worried he won't get any.

The rap star is leading the list of nominations and already has 10 Grammys to his name, but it seems the doubts are still creeping in.

He's up for Song of the Year for 'Love the Way You Lie', as well as the coveted Album of the Year trophy for Recovery.

Bob Dylan fans may already be aware of a forthcoming DVD called ‘Revealed’ which is due out in May via Highway 61 Records and Amazon UK have now confirmed an audio CD with the same titled for May 3rd.
 
Notes about the release:

When Bob Dylan turns 70 in May 2011, his iconic career will have spanned five decades. Yet, a true portrait of the reclusive “voice of the generation” has eluded Dylan fans. Through exclusive insider interviews, and never-before-seen photos and footage spanning Dylan’s 50-year career, Bob Dylan Revealed offers an intimate biography of who Bob Dylan was, and who he is today.
