It looks like Allstar Weekend will be missing a member of the band on their upcoming tour. They posted on their facebook this morning:
"To our fans: We wanted you to be the first to know that Nathan will not be joining us on our upcoming shows or on the Selena tour. He is home dealing with some personal matters and is taking some time off. Everything is okay, so there is nothing to worry about. We will see you soon ♥"
We hope everything is ok Nathan!
