Will Harry Potter die?
It's the question on the minds of billions of people across the galaxy as they await their favorite wizard's fate in Harry Potter and the Deathly Hallows.
"I was in a hotel room on my own. I was sobbing my heart out," she tells the BBC's Jonathan Ross.
"I downed half a bottle of champagne from the mini-bar in one and went home with mascara all over my face. That was really tough."
Wow. That's more emotional than we got when we heard Brody Jenner had turned his man-whore attention to Hilary Duff. Stay away from him, girl!
But Rowling also felt other emotions upon completing Harry Potter and the Deathly Hallows, due out July 21.
"Finishing the book is a relief," Rowling told People magazine. "I can feel more relaxed. I felt euphoria, devastated, when I finished one chapter near the end. I absolutely howled, it had been planned for so long."
The author also divulges her inspiration for the three main characters. Harry Potter, she says, is "totally imaginary," but Hermione Granger (Emma Watson) is a bit like her younger self ("I was quite swotty [nerdy] when I was a kid") and Ron Weasley is "a lot like my oldest friend Sean."
Finally, there is one Harry Potter spoiler the writer will reveal: the word "scar" is NOT the final word in the book.
"It was so for ages, and now it's not," she says. "Scar is quite near the end, but it's not the last word."
That doesn't help us much, though. Nevertheless, we're more excited for this to be released than Nicole Richie is to have a baby.
