Fans were asked to submit questions for the 'Twilight' actress about the fragrance, Florabotanica, on their site ahead of her session next week, reported Mirror online.
But a lot of upset 'Twilight' fans have taken it over, asking Stewart personal questions.
Some of the nasty comments include: "Why are you doing this? You've never worn perfume before."
"Do you love Robert? Or do you cheat Robert???" another fan asked.
An angry fan said, "Does Rupert like this smell on you?"
Another posted, "What happened to Bear?" in reference to the Pattinson and Stewart's dog.
Some people asked more interesting questions, like, "What's your favourite letter in the alphabet?"
