Singer songwriter Fiona Apple's tour will be delayed as she tends to her dying dog, the singer has put her pet before her fans, but we're sure her fans will understand. The singer writes in a handwritten letter posted to her Facebook profile: "Janet has been the most consistent relationship of my adult life, and that is just a fact."

Apple goes on: "She has Addison's Disease, which makes it dangerous for her to travel since she needs regular injections of Cortisol, because she reacts to stress and to excitement without the physiological tools which keep most of us from literally panicking to death. Despite all of this, she's effortlessly joyful and playful, and only stopped acting like a puppy about 3 years ago." The letter continues to say the "decision is instant" to stay with her friend rather than go on tour, while she explaines, "I just can't leave her now, please understand. If I go away again, I'm afraid she'll die and I won't have the honor of singing her to sleep, of escorting her out."

Apple made the news recently, when she was arrested for hashish possession on Wednesday at a West Texas town after a Border Patrol drug-sniffing dog detected marijuana in her tour bus.
