David Cook appreciates the support he's receiving from fans while on tour, however the American Idol seventh-season champ also wants some of his more aggressive aficionados to back-off a bit.

"I have to address some behavior that has become disturbing," wrote Cook in a Sunday posting on his MySpace blog.

"We pride ourselves on being accessible to you as fans, but in contrast, we do enjoy what little privacy we can muster. To that end, the efforts by some fans to find our hotel rooms, call our hotel rooms, attach things to our bus, etc., is something I have to condemn."

In addition, Cook said his relationship with fans "only works when it remains healthy for both parties."

"Should this behavior continue, the only thing we can do is take more preventative measures to maintain our privacy, which in turn makes us less accessible to you," he wrote.

Cook said that he hopes fans don't view his request as "harsh."

"I merely want to nip this in the bud so we can continue to have a great experience with all of you at the shows we have coming up," he wrote.

The seventh-season Idol champ began his 37-date concert tour last month.
