Lloyd Bishop/NBCAll dogs may go to heaven, but Fiona Apple wants to be with hers for as long as she can while she's still around.
The chanteuse has canceled the South American leg of her current tour in order to be with her dying pooch, Apple announced Tuesday on her Facebook page.
In a touching, four-page handwritten letter, the 35-year-old singer speaks warmly, candidly and—oftentimes—heartbreakingly about her 14-year-old Pit Bull Janet, who she said suffers from a chest tumor.
"Janet has been the most consistent relationship of my adult life, and that is just a fact," she writes about her dog, who was rescued after being abused by dogfighters.
The songbird goes on to describe how the pooch, who "was under the piano when I wrote songs," has remained "my best friend and my mother and my daughter, my benefactor, and she's the one who taught me what love is."
"I can't come to South America. Not now," she shares, adding, "I am asking for your blessing."
Apple recently wrapped up the North American leg of her tour and was set to kick off her South American dates on Nov. 27 in Porto Alegre, Brazil, before heading to Argentina and Mexico.
