The Jonas Brothers are taking their show on the road with Joe Jonas' girlfriend Demi Lovato gearing up for the tour as well.

The brothers announced that they will be embarking on a three continent world tour with Lovato as their special guest. The Jo Bros. and Lovato will perform their hits in addition to singing some tracks from their Disney Channel original movie "Camp Rock" and its sequel "Camp Rock: The Final Jam."

Joe Jonas and Lovato made their relationship official this year with Joe telling Ryan Seacrest on his KIIS FM radio show, "We've been best friends for the longest time and now we're just kind of taking the next step and it's been really fun. We're having a great time. .... I guess we kind of figured that one day it would happen but we didn't feel like it was the right time."

Lovato added, "Being best friends for a while, over time feelings grow, and for me, as much as I wanted to deny it, the feelings were always there."

Concert tickets for the upcoming tour go on sale beginning Saturday, May 15.
