Their Mexican fans will have to wait to see their favorite curly haired musicians, because their upcoming concerts have been canceled due to the ongoing swine flu scare.

Billboard magazine reports that Kevin, Nick and Joe have postponed their May 17 "Burnin' Up" tour stop at Arena Monterrey in Mexico "due to health precautions in the whole country as a consequence of the outbreak of the A(H1N1) flu." The two May 17 shows will be moved to July 31, where the brothers will be joined by fellow Disney singer Demi Lovato. 

Hey, it's not like their fans South of the Border are going completely without.  For now, they can get their Jonas fix on the Disney channel. 

The boys are currently hard at work preparing for their upcoming World tour for their fourth studio album, Lines, Vines & Trying Times, which drops June 14 . 

The boys tweeted this afternoon, "A little break from rehearsals...hanging with the boys from Honor Society...can't wait for tour to start," along with this picture.
