How's this for a blockbuster double bill?  Maroon 5 and Kelly Clarkson are hitting the road together.

The two acts are teaming up for the 2013 Honda Civic Tour, which is now in its 12th year.  It kicks off August 1 in St. Louis, Missouri and will run through early October.  Also on the bill on select dates will be Maroon 5 keyboard player PJ Morton, performing solo, as well as one of Adam Levine's The Voice team members, Tony Lucca, plus Rozzi Crane, the first artist Adam signed to his label, 222 Records.

In addition to lots of music at each tour stop, fans can enjoy checking out one-of-a-kind Honda vehicles that have been customized and autographed by the participating artists.

In a statement, Adam said, "We are very excited to team up with the Honda Civic Tour,. Kelly, PJ, Rozzi and Tony are all such unique and amazing artists. I’m really looking forward to hitting the road with them. Each night will be a great night of music.”
