Big Time Rush gets together for some pictures backstage at the House of Blues in Los Angeles on Monday night (4/1/2013).

The guys — Carlos Pena, James Maslow, Logan Henderson and Kendall Schmidt — performed an acoustic set after tour mate Victoria Justice hit the stage.

James shared with Ryan Seacrest of their upcoming tour, “We’ve known Victoria for years now so having her join us on tour is like having an old friend come hang all summer! A beautiful and talented old friend that is!”

Kendall added, “We are so stoked to be going on the road again because nothing makes us happier then seeing our fans sing and dance along! Can’t wait for them to hear our new stuff!”
