Usher and Alicia Keys really racked up the nomiinations for the Billboard Music Awards, to be held Dec. 8 at the MGM Grand Garden Arena in Las Vegas and set to air live on Fox.

Usher is up for awards in a whopping 13 categories while Keys is right behind him and up for 12 awards.

Keys is up for artist of the year, female artist of the year, Hot 100 songwriter of the year and Billboard 200 album of the year for The Diary of Alicia Keys.

The two are the only finalists for R&B/hip-hop single of the year (Usher's "Burn" and "Yeah!" and Keys' "If I Ain't Got You" and "Diary").
