The ACM (American Country Music) Awards are tonight on CBS but the jabs from the hosts have already begun.  Hosting the ACM Awards this year are country singing stars Blake Shelton and Luke Bryan.   Shelton has warned Bryan not to make fun of Taylor Swift unless he wants to take on the wrath of the millions of Swift fans who quickly come to her defense on social media.  Even worse, they joke she might write a song about him.  

The two singers have dubbed themselves 'Bluke' for the show tonight.  Both are known for their humor and crazy antics so people are expecting plenty of unscripted moments tonight, especially by Shelton as he is the more seasoned of the two.  This is Shleton's second straight year hosting the ACM's, he co-hosted with country legend Reba 

Blake Shelton is up for Entertainer for the Year along with Taylor Swift, Jason Aldean, Miranda Lambert and Luke Bryan.  Swift won this award last year.  Shelton and Bryan are also up for Male Vocalist of the Year tonight. 

Taylor Swift rules 2012 selling more albums and more concert tickets than anyone in country music.  

Last year Taylor Swift was not sure how to react when Shelton and Reba McEntire joked about rumors her date with NFL star and heart throb,  Tim Tebow.

Blake Shelton had a great year last year.  He was a judge on the hit tv show "The Voice" and released his Christmas album so it's no surprised he's been nominated for Entertainer of the Year at this Sunday's Academy of Country Music Awards.
