As if there wasn't already enough reasons to hate New Kids on the Block and the Backstreet Boys. The former teen pop throbs have signed up "Glee" star Matthew Morrison as the opening act of their summer co-headlining tour, which means the singer/actor better known as Mr. Schuester is bailing on his own solo tour, including the June 18 kick-off at the Orpheum Theatre. Refunds to the show are now being given.

Local Gleeks will still have the chance to see Morrison when the NKOTB/BB tour lands July 15 at Target Center. However, they will see a shorter set and likely have to sit behind current ticketholders to the July 15 show. On the other hand, NKOTB/BB fans (who are probably on the upper end of "Glee's" age demographics) have to be pleased with the added entertainment value.

"This was an opportunity I couldn't pass up," Morrison said in a statement. "I am so appreciative of my fans and I'm planning to give them a great show."

Fans probably shouldn't get too angry with Morrison. A good explanation for this switcheroo might be that his own tour was not selling that well. Even if it was, he stands to gain a lot more exposure on the Kids/Boys tour, which is turning into one of the summer's biggest tours. Yeah, go figure. There's also still the official "Glee" tour with most of the kid actors, which is coming June 1 to Target Center -- unless maybe Lady Gaga or Britney offers them an opening slot.
