Blake Shelton and Luke Bryan will be hosting this Sunday's ACM Awards show on CBS.  In this supposed behind the scenes look, Blake pokes a few jabs at Luke over his lack of experience and "pretty boy" looks.  Check out the video.

After spending a few years as second banana to Reba on the ACM Awards, Blake Shelton looks like he's ready to take the lead.

Don't think Luke is going to be a pushover for Blake's antics, a few weeks ago Luke released his own video commending the ACM's on picking the right host to help "pick Blake up." Check it out here. The show airs on CBS this Sunday night at 8. Check out the list of ACM Nominations and vote for your favorite here.
