Allstar Weekend will be left to perform minus one of their star players. The teen heartthrobs took to their Facebook page on June 20 to announce that guitarist Nathan Darmody will not be joining them on their upcoming tour with Selena Gomez or other prior dates.

The band issued a statement saying, "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 ♥."

The statement garnered hundreds of comments from well-wishing fans. One wrote, "Breaks my heart since Nathan is my fav, but its good that he is putting himself first and taking care of things. I wish him all the best, and I look forward to seeing the rest of the lovely gentlemen in August!" Another fan worried, "Hopefully this isn't the start of the band breaking up : ( but feel better Nathan we love you, it wont be the same."

Allstar Weekend has been touring in support of their upcoming album, All The Way, due out July 19. Their single 'Not Your Birthday' is featured on Disney's Prom movie soundtrack. The boys will join up with Selena Gomez on July 30 in Boca Raton, Fla.
